Look for a LinkedIn IPO, but not in the near future. Company co-founder and executive chairman Reid Hoffman has revealed his (and his investors') exit strategy, even if it could take a while to get there. Any social media company IPO would take a while to get off the ground in this market, since companies are being incredibly cautious. So, "not anytime soon" could coincide with a change in market conditions ... but Hoffman stopped well short of that.

At an event in London to celebrate LinkedIn's hitting the 3 million user mark in Britain, Hoffman said about the company's IPO prospects, "Probably at some point a balance will occur when that's the right thing. That will not occur in the near term." Worldwide, LinkedIn has 53 million members.

Google (GOOG) just picked up another promising startup in its effort to gain some ground in the online visual advertising market. Teracent, which was formed three years ago, is becoming part of the search engine giant.

Yahoo! (YHOO) currently leads the market in display advertising sales, and Google has been trying push into the space. Last year, this led to its acquisition of online ad service DoubleClick, but that was a first step rather than a total solution to Google's display ad ambitions.

Twitter is on the prowl. Though it made its last acquisition more than a year ago, company founder Biz Stone said on Tuesday that it's looking to add to the stable. There aren't any specific targets yet -- at least none revealed -- and Twitter is keeping its options open. The likely pool of potential acquisitions consists of third-party Twitter application developers, which is largely responsible for the micro-blogging service's growth in popularity.

Stone, one of Twitter's founders, said at a Tel Aviv news conference, "As our attention is grabbed by some of these developers, we will take a hard look at them." This refers to companies that develop applications for Apple's (AAPL) iPhone and Research in Motion's (RIMM) Blackberry. It also refers to developers for the Web and desktop, such as HootSuite and TweetDeck.

Hewlett-Packard (HPQ), the famous maker of printers and PCs, and a colleague of entities such as Microsoft (MSFT), Dell (DELL), and International Business Machines (IBM), issued Q4 results on Monday after the end of the trading day. Revenues didn't impress me, as sales saw a decline of 8%. Net income, however, was better. On an adjusted basis, earnings per share increased 11% to $1.14.

Also doing well was the operating margin. The adjusted metric increased 170 basis points during the quarter. The annual statement of cash flows should look good to any long-term shareholder. Management still had cash left over from operations after share repurchases, dividend obligations, and capital spending.

Twitter calls Google (GOOG) a "good role model," but says it isn't ready to rush down the road to advertising.

Nonetheless, an ad-based revenue model is something that cofounder Biz Stone says they "will be looking to do down the line." But, for now, he continues, Twitter is focused on "creating value for our users." For now, revenue generation ideas are being put on paper, "and we're definitely going to get to them," Stone says.

Take the Nook off your Christmas list. The new e-reader from Barnes & Noble (BKS) has already sold out, and more won't be available until after the holiday has passed. The next batch will be available, at best, by January 4, 2010.

In a statement, the company said, "While we increased production based on the high consumer interest, we've sold out of our initial Nook allotment available for delivery before the holidays." If you still want to give the device as a holiday gift, Barnes & Noble will give you a gift certificate to tide the recipient over until the device itself comes around.

Google (GOOG) is letting a few developers peek behind the curtain. The early look the company's new operating system, Chrome, is happening in true Google style: by invitation only. When it's released, which should be in time for the holidays, developers will be able to bang away at an open source solution, tapping an army of volunteers who are eager to work for bragging rights.

The open source version is called Chromium OS, which will hit the market a year before the "consumer" version is ready, which is how Google will be able to tap the wisdom of developers around the world. In a blog entry, Google explained, "This means the code is free, accessible to anyone and open for contributions." The project includes the code base, user interface experiments and some preliminary designs, all of which can be used for ongoing development efforts. To energize the potential base of contributors, Google said that "development will be done in the open from this point on."

Yahoo! (YHOO) is the latest company that wants to optimize its search results for Twitter. This follows moves by Microsoft (MSFT) and Google (GOOG) to integrate Twitter data into their search results. Unlike its competitors, however, Yahoo! wants to do this without spending a dime (well, without giving a dime to the hot new social media platform).

Twitter's microblogging service has become famous not only for its rapid growth but also because it's found no way to turn it into revenue. Its recent discussions with Microsoft and Google demonstrated that Twitter can indeed bring in some cash -- by licensing its data for use in fine-tuning search engines. With two of the top search engines now optimizing for Twitter, it was only a matter of time before Yahoo! would rush to join the party.

TheStreet.com's Jim Cramer says traders who focus on the negative will pounce on this poor report.

Thanks for nothing, Dell (DELL) (Cramer's Take)! Given that this market seems to care less about the good like NetApp (NTAP) (Cramer's Take), Ross Stores (ROST) (Cramer's Take) or Limited (LTD) (Cramer's Take) and is focused on the bad, like the semi-downgrade from Bank of America Merrill Lynch, I am sure that Dell will be viewed as part and parcel with the downgrade.

I can't stand Dell. I actually slam it in Getting Back to Even, taking a chance that it would get its act together and make me look bad on the very quarter the book is released. Looks like that was a lot of worry for nothing.

After-hours traders punished Dell (DELL) stock Thursday, following a weak third quarter earnings report from the technology giant.

Going into the afternoon earnings release, analysts had been expecting to see the company show earnings of 28 cents per share. Actual earnings came in much lower at 23 cents per share.

Every day, it's becoming clearer that e-readers will be the hot holiday gifts of 2009. Amazon (AMZN) is obviously in the game with its Kindle, with which it took an early lead in the industry. Barnes & Noble (BKS) has made a play with its new Nook reader, applying some pressure to what was once a wide open space.

Even though we're still short of Black Friday, the weeding process has begun. Sony (SNE), which is also in the e-reader market, has revealed that it makes no guarantees about delivery by Christmas.

Once upon a time, Mac users could brag they were much safer from malicious electronic attacks. After all, in the days before Google (GOOG), when Microsoft (MSFT) was the only uber-player in town, Windows was the perpetual malware target. Phishers, however, aren't discriminating; they're just looking for an account to plunge. So, both Apple (AAPL) and Microsoft users are threatened. Virus writers do tend to focus on the Windows operating system, which owns 90% of the OS market, but phishers are platform independent.

Phishing involves attempts to get a user to reveal information about their accounts. Once the soon-to-be victim clicks that link or fills out a form, the "transaction" is complete -- no operating system interaction necessary. As a result, there really isn't any advantage to using a Mac over a PC.

Amazon, Inc. (AMZN) is in the clouds. So are Google, Inc. (GOOG), EMC (EMC) and Cisco (CSCO). Now, Microsoft Corporation (MSFT) is joining them, having announced on Tuesday its new Windows Azure cloud computing system. The new product will be released on January 1, 2010 -- a new solution for a new year.

Azure will deliver an online platform for the software development set to build their own mousetraps and provide plenty of storage space for users. Testing began a year ago, and full live version will be celebrated next year. For the first month, Azure will be free. The charges start in February.

An unemployment rate of 10.2% means that serious jobseekers are using every tool they can find. So, it's not at all shocking that social networking tools top the list, with LinkedIn, Facebook and Twitter leading the charge. Openings are being tweeted, hints of a new position are being monitored and hot candidates are being hit up directly, even if they aren't saying they're on the prowl for a new gig. Social media is a tool to use in a job hunt but not necessarily the only one, according to Challenger, Gray & Christmas. Instead, it makes sense to balance a search with many tools.

John Challenger, CEO, says, "The job search has changed radically over the last two decades with the advent of electronic mail, the internet, social networking, smart phones, etc. However, it is important to remember that all of these technologies simply enhance the job search; they will never replace the face-to-face connections that are critical to a successful search." But, he continues that "we feel that these new networking tools are essential and now advise all of the job seekers going through our program to open LinkedIn accounts and to consider other services such as Facebook and Twitter.

Imagine taking the personal connections and interactions that occur every day on the likes of Facebook and Twitter... and bringing them to bear on an education. To a large extent, this hasn't been done yet, but the potential is profound. In a new report by the Center for Community Survey for Student Engagement, two-year programs aren't taking advantage of the tools at their disposal -- plenty of growth is still possible. Kay McClenney, director of the CCSSE, says, "Colleges are not taking advantage of that particular set of tools for making connections with students to the extent that they could."
