With the overall economy slumping, the tech industry is taking its fair share of hits. We'll keep updating the chart below as news of company changes comes in. See our complete coverage of how the tech sector is faring here: Tracking the tech downturn.

If you want a real-time view into the world of layoffs, use this Twitter search. But we recommend having a stiff drink first.

Social-media pioneer LiveJournal is the latest company to announce a round of layoffs, trimming down its employee head count in its San Francisco and Moscow offices.
A statement from the company came after a rumor on gossip blog Gawker suggested that a shocking number of LiveJournal employees--20 out of 28--had been cut. LiveJournal clarified that it was "about a dozen" cuts, amounting to about a fifth of the company.
"LiveJournal Inc.'s headquarters, technical operations (and servers), legal, administration, and the customer service teams will remain in the United States," the release explained. "LiveJournal's global product development and design will now be coordinated out of its Moscow office. The pooling of resources between the U.S. and Russia will allow the company to build a stronger business model, well positioned to guarantee the long-term success of LiveJournal."
Yahoo veteran Matthew Berardo, who was hired as general manager of the service less than a year ago, was affected by the layoff.
LiveJournal was founded nearly a decade ago by OpenID creator Brad Fitzpatrick, who sold the company to blog software firm Six Apart. But that led to widespread reports of management difficulties, and late in 2007, Six Apart resold LiveJournal, phenomenally popular in Russia, to the Moscow-based software company SUP.

Charles Schwab improved its online trading platform Tuesday with the introduction of new features for its site, StreetSmart.com. According to the investment firm, clients will now have real-time performance reporting for closed positions, new short-selling tools, and more order types. The app will also feature new tabs for realized gain and loss data and information on shorting securities. The updates are available now on the Schwab service.
Privus Mobile, a company that provides mobile calling services, announced Tuesday that its Caller ID app is now available through Handmark stores, as well as mobile stores that offer apps for Windows Mobile, BlackBerry, and Palm devices. Privus Mobile's Caller ID feature gives users a cross-carrier option to find out who is calling, regardless of whether their name is included in the user's contacts. The app is available now without cost, thanks to a free trial period.
Move Networks, the company behind online video streaming for Fox, ABC, and a variety of cable networks, streamed 180 million hours of video last year, it claims. 100 million hours of that coverage was in HD. The company estimates that it provided video for 55 million unique viewers during 2008 and it expects even more viewership during 2009 as more professional content makes its way to the Web.
TechCrunch is reporting that Clearspring, a widget distribution firm, has laid off several of its staff, though the company's CEO, Homan Radfar, would not say exactly how many employees were affected. Radfar told TechCrunch that the layoffs occurred during the "fourth quarter of 2008." For more layoff information, see CNET's Layoff Scorecard.
RipCode, a provider of Web and mobile video streaming services, announced Tuesday that it raised $12.5 million in funding to help it gain worldwide traction. The round was led by Granite Ventures, along with Hunt Ventures and Vesbridge Partners.

Skype 2.8 for Mac will ship on Tuesday, with new features including screen sharing and an integrated Wi-Fi hot spot connector.
Available only for Mac OS X at first, the new version will add screen-sharing capabilities to the app's voice, video, and chat communications features. Skype spokespeople told me that users will be able to run all four channels at once with acceptable performance.
Screen sharing is useful in business settings (I get a lot of demos over apps like Webex, for example), but it has personal applications as well: People could share photographs, and presumably videos as well, using the feature.

Skype is also getting a feature that will allow users to access WiFi hotspots on the Boingo network for 19 cents a minute. The funds will be deducted from users' Skype accounts. Boingo has about 85,000 hot spots worldwide, a Boingo rep told me. TMobile, the primary Wi-Fi provider at U.S. airports, is on the Boingo network.
The Wi-Fi access feature makes Skype a more useful product for people who use the VoIP app from their Mac laptops, and the per-minute payment scheme makes sense for highly mobile users for whom buying access by the hour or month would leave a lot of unused credits behind.
Skype co-founder Nicklas Zennstrom also started a Wi-Fi network called Fon, but Skype 2.8 doesn't yet integrate with that system.

Disruptive Telephony covered other new features in Skype 2.8, including a new way to update your Skype "mood" and to follow users in a Twitter-like fashion, bigger Avatar images, and a new way to manage and prioritize chat windows.
Also, regarding Boingo: That company announced a new Apple product: A connector app for the iPhone and iPod Touch. For $7.95 a month, users of those devices can access the entire Boingo Wi-Fi network. For U.S.-based iPhone users on the AT&T network, this is not such a great product since AT&T-provided Wi-Fi is now free for them, but international users and travelers, and iPod Touch users (perhaps those who use TruPhone for VOIP calls) may find it a good deal.
I'm as guilty as the next person for having a social network portfolio that's too big. Aside from my Twitter account, I belong to Plurk and Identi.ca, and although I use Facebook most often, I still have MySpace and Hi5 accounts.
But now that 2008 has passed and it's time for us to evaluate what we did last year and try to improve upon that for 2009, why don't we start by cleaning out our social network portfolio and start using only those services that we like best in each category? After all, spending more time on multiple services isn't nearly as rewarding as getting more quality time with the best services, right?
Social bookmarking keeper: Delicious

Social bookmarking services are extremely handy when you want to remember a site at a later time, but that doesn't mean they're all created equal. In fact, Delicious, the leader in the space, easily sets itself apart from competitors like Ma.gnolia, Diigo, and ZigTag by boasting a better interface, more users, and better tagging, which makes it easier to find and share bookmarks.
Although Diigo's highlighting options are useful, ZigTag's semantic technology tries to improve bookmarking, and Ma.gnolia aims at providing a more thorough solution, none compare to Delicious. Yahoo's social-bookmarking service now features a streamlined search function, which makes finding bookmarks simple, and its new design makes it the most intuitive social-bookmarking service on the Web. But Delicious' most useful offering--its Firefox add-on--has nothing to do with the site at all. By installing the Delicious add-on, users can tag pages on-the-fly without being forced to visit the Delicious homepage. Granted, its competitors have Firefox add-ons as well, but after using each, it quickly becomes clear that they simply don't work as well as the Delicious tool.
Taking all that into account, I simply don't know why it's worth using another service besides Delicious. It's a superior tool with more convenient options, offering the same basic functionality as its competitors. It's the cream of the social-bookmarking crop.
Micro-blogging keeper: Twitter
I'll be the first to admit that I complain about Twitter as much as the next person, but after using competing services like Identi.ca, Jaiku, and Plurk, it's not hard to figure out that it's the only worthwhile micro-blogging tool.
Granted, Twitter still doesn't offer groups and I wish it had an element of open source like Identi.ca, but the sheer number of users who comment each day on Twitter makes it the best choice for your social-networking portfolio. If you want to be a part of a community that's both lively and engaging, you won't find it anywhere else but on Twitter. And now that it's more reliable and the Fail Whale is an occasional annoyance instead of a daily occurrence, Twitter has become an even more compelling service.
As the best place to find friends, colleagues, and thought-leaders in any industry, Twitter is the obvious choice as the only micro-blogging service that should be found in your social network portfolio.
News Aggregation keeper: Reddit
Trying to find the ideal news aggregator on the Web can be difficult. Depending on your definition, there's conceivably hundreds of services that package the best stories into one page. But it's the "social" news aggregation services, like Digg, Reddit, and StumbleUpon that lead the pack. And although Digg is the most popular service in that grouping, I'm a firm believer that Reddit deserves to stay in your portfolio as your chosen news aggregation service.
Normally, I would pick the social site that offers the largest and most engaged community. But when it comes to news aggregation sites, Digg simply doesn't cut it. Sure, it's the biggest and arguably the most important to content sites, but that alone doesn't make it the best. Instead, I find Reddit's site design, while simple and ugly to some, incredibly useful and designed to help users find the best stories as quickly as possible without gaudy extras. But the most important differentiating factor working to Reddit's advantage is its community. It might be smaller than Digg's, but generally, the comments on each story are more edifying and lack the invective that has become a staple for Kevin Rose's brainchild.
Reddit may not be the biggest, its site design may be odd, and its community not as rabid, but in terms of providing interesting stories on a slew of topics without as much "gaming," it leads the pack and deserves to be in your social network portfolio.
Social Network keeper: Facebook

Choosing the single social network to use while ditching the rest isn't easy, since most of us have friends scattered across Friendster, Hi5, and MySpace. But it's because of those few friends still clinging to the past that we hold on to all those social networks. Enough is enough. It's time to rebuff the rest and stick to Facebook.
Why choose Facebook when MySpace is still the world's most popular social network? It's simple: Facebook doesn't have the awful design found on MySpace profile pages, offers a huge, engaged community, and most importantly, it's growing at a rapid rate, which means all those friends who still hang out at Friendster, LiveJournal, or even MySpace are starting to make their way to Facebook.
MySpace still provides value and Hi5 could be a significant competitor in just a few short years, but for now, Facebook, with its addicting features, applications, and growing community, should find its way to your portfolio as you leave the others out.
Video site keeper: YouTube

Maybe YouTube is the safe choice for the only social video site you should keep in your network portfolio, but I simply don't see how anyone can choose anything else. Vimeo is nice, but much of its content is barely watchable and while Metacafe is still an interesting site worth visiting, it doesn't provide the professional content that YouTube does.
And it's that professional content that I find most valuable when it comes to YouTube. Sometimes, I want to find a music video that isn't available elsewhere and YouTube will have it. And when I'm feeling nostalgic and I want to watch an old clip from The Wonder Years, it's sitting on YouTube waiting for me. As a bonus, some of the user-generated content is pretty good too, though most of it is strange.
I know that anyone can make a case for why practically any user-generated video site on the Web should be the exclusive service in your portfolio, but when it comes to finding the obscure, professional, or just plain weird, YouTube is the only place to go. All the others are practically useless.

CNN anchor Rick Sanchez wasn't really high on crack this morning, and the reason his Twitter feed said so wasn't the phishing scam that's been going around--it was a lone hacker, the microblogging service said later on Monday.
"The issue with these 33 accounts is different from the Phishing scam aimed at Twitter users this weekend," a post on the Twitter blog explained. "These accounts were compromised by an individual who hacked into some of the tools our support team uses to help people do things like edit the e-mail address associated with their Twitter account when they can't remember or get stuck. We considered this a very serious breach of security and immediately took the support tools offline. We'll put them back only when they're safe and secure."
The same hacker was responsible for compromising a number of Twitter's most popular accounts, including those belonging to pop singer Britney Spears, media outlet Fox News, and President-elect Barack Obama.
Twitter has said, meanwhile, that the phishing scam--which used messages from Twitter friends to trick users into entering their user names and passwords into a bogus log-in screen--is under control. "Our on-call team was able to attend to the matter quickly and prevent too many people from being affected," Twitter's blog post read. "Our support team is definitely going to have a busy week because we reset a bunch of passwords just to be on the safe side."
Firefox extension Site Launcher (download) lets you replace your bookmarks toolbar with an overlay window of links that can be pulled up at any time using a simple keyboard shortcut. You pick which sites you want on the list, and a one-letter keyboard shortcut is given to each. When pulled up, you simply hit the key for the site you want and it goes straight to it. Once you've memorized which sites are on your list, you can make use of an alternate key combination that lets you skip to each site without having to view the menu at all.
The extension comes with a handful of popular sites built in, although you can also start from scratch with your own. You also have several color and menu style options including setting the maximum number of columns you want, and how transparent the window is.
If you're a laptop or Netbook user looking to get the convenience of a bookmarks toolbar without sucking up the screen real estate, this is a great way to save some space.
Here's a quick demo video of how it works:

Outlook plug-in maker Xobni has raised a $7 million series B round of funding led by Cisco. Previous investors from the series A funding (about $4.1 million) also participated in this round.
Xobni is an e-mail add-on that analyzes your in-box to give you context around the people you communicate with. Recent updates also correlate against social sites like LinkedIn to provide even more information on people.
A company spokesperson told me that the funds will be used to add features and stability to the application, and to knock out a few remaining bugs that prevent some users (like me) from using the Xobni add-on. At the same time, the funds will help the company weather the tough economy. The company blog discusses a "focus on our premium business, and address the growing interest from our enterprise customer base," which meshes with Cisco's business model.
