One of the top performers in the U.S. growth fund sector has lost his appetite for tech. Jerry Jordan has booted almost all his Apple (AAPL) holdings from his portfolio, and he's done the same with Google (GOOG). Both, Jordan says, have become too expensive. In fact, he's getting out of almost all U.S. and European tech companies for that reason -- and is turning his attention to China.

Jordan tells Reuters, "The growth [in China] is much faster, it's much more of a green field opportunity."

Facebook is implementing a new stock structure to make sure the founders retain control, immediately causing rumors about an impending initial public offering. Why would Facebook need Class A and Class B shares otherwise? Under the new structure, which is similar to Google's (GOOG), Mark Zuckerberg and other early entrants wouldn't have to worry about yielding the floor to outsiders when if the company goes public.

The stock structure was adopted to ensure that existing shareholders keep control on voting issues, according to Facebook statement. No details were given as to who the winners are in this arrangement, but a Wall Street Journal report says that, according to its sources, all current shareholders would be converted to Class B shares, which carry 10 times the voting rights of Class A shares.

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.

Often, we confuse winning with being the best. This isn't always the case. There are plenty of ways to get ahead when you don't have the top product on the market. The smoke-filled backroom meetings may be a thing of the past, but the net effect lingers. This is exactly what went down, according to a Reuters report, when Microsoft (MSFT) had a chat with News Corp (NWS).

Microsoft suggested a relationship with News Corp which would involve the latter's yanking its news sites from Google (GOOG) ... for a fee, of course. This would cost the search engine giant -- which is also a news aggregation giant -- access to some hefty publications, including the Wall Street Journal, the Sun and the New York Post.

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.

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.

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.

BT Group, which virtually owns the UK telecommunications market, isn't waiting for Google (GOOG) to launch a full attack. The company probably expects to be under assault from the search engine (and advertising and e-mail) giant, so it's taking early action. Google Voice is still being tested, but words like "free" and "powerful" and "internet-based" are bound to inspire fear in even the most established of companies.

To protect itself from the eventual attack from Mountain View, BT picked up Ribbit Mobile, and testing is in progress. Ribbit's technology has some overlap with Google Voice and even beats it with a few capabilities, according to Bloomberg. Ribbit just launched its beta product this month. It allows either the user's current phone number or a new one from Ribbit -- which is no different from Google's alternative. The product suite is generally the same, with phone- and web-based voicemail retrieval and automatic transcriptions that can be sent by text message or e-mail. For an extra fee, BT's Ribbit does provide human transcription, though it is free during testing. And, calls can be taken directly from a computer, using a microphone and speakers.

The future investment stars are already with us. The NYSE Financial Future Challenge, operated by the NYSE Foundation, By Kids for Kids, K12 Inc. and the United Investors Association, is in full swing, with five finalists just identified. To reach this level, the participants had to develop a new product, idea or process that would "excite, educate and motivate their peers" to become interested in the financial marketplace. The eventual winner lurks within this subset and will receive a $2,500 prize -- a great way to get that portfolio started. And, he or she will be feted at a closing bell ceremony at the NYSE (NYX) on January 11, 2010.

The finalists presented a variety of ideas which are sure to generate some buzz. Kelsey Foss, a 12-year-old from Mountainville, NY, proposed a new television show, "Stock Market Tycoon Idol," which would harness the popularity of reality TV while amping up the content. The program would involve the journeys of 10 kids as they seek to make money or lose it, with the possibility of becoming virtual millionaires along the way. The show would be set at a mock NYSE studio on Wall Street, and exports would be brought out to mentor the contestants. The reality TV reach would help engage a younger audience.

Even the thought is hard to believe for anyone who's been watching Apple Inc. (AAPL) over the long run. Once upon a time, the company was presumed dead, while Microsoft Corporation (MSFT) continued its march to market dominance. Today, Apple's $180 billion market value is evidence of a new era. Though it's still behind Microsoft's $250 billion, the company's rapid ascent and substantial market presence make at least speculation of catching up to the Redmond giant worth a few minutes of thought.

Microsoft is currently the most valuable technology company in the world, according to a Reuters report. Even Google, Inc (GOOG), with its astounding brand recognition and position as gateway to the internet, is worth "only" $136 billion. Apple, which was once considered a computer company that sold into education and appealed to some graphics geeks, has reasserted itself as a major global presence.

The vision of Clearwire (CLWR) is definitely ambitious: to "give you faster Internet at home, at work and on the go, so that people everywhere will have the magic of the Internet with them all the time." This means building a sophisticated network across the country, which does not come cheap.

Tuesday, Clearwire announced yet another financing round, which comes to $1.56 billion. The investors include Sprint Nextel (S), Comcast (CMCSA), Time Warner Cable (TWC), Intel (INTC), Eagle River Holdings LLC, and Bright House Networks LLC.

Out of the kindness of its ginormous heart, Google (GOOG) is giving holiday travelers a bit of cheer this season, providing free Wi-Fi in 47 U.S. airports starting today and running through January 15. As a bonus to Virgin America passengers traveling within the continental U.S., Google is providing in-flight Wi-Fi as well.

Of course, the Web search giant has an ulterior motive. In a statement, a Google spokesperson said: "This is one of our holiday gifts to our users, and when you connect, we also hope you'll take the opportunity to try some of the latest Google products."

For News Corp. (NWS), MySpace is the mistake that keeps on costing. It's bad enough that Murdoch's empire paid $500 million for the social networking platform shortly before Facebook knocked it from the premier spot in the social media beauty pageant, but now we also know that News Corp. has committed $350 million to office space for MySpace that will never be used.

News Corp is shelling out more than $1 million a month for 420,000 square feet in Playa Vista, near Los Angeles International Airport. The deal was signed in August 2008 by Peter Levinsohn, former president of the Fox Interactive Media Unit. At the time, he issued a chest-puffing memo claiming it was "the single biggest real-estate transaction in Los Angeles in the last 25 years." Fortunately, he didn't mix the word "genius" in there at all.

If Amazon (AMZN) was comfortable with its spot atop the e-reader market, it just got a wakeup call from Barnes & Noble (BKS). The brick-and-mortar book retailer's e-reader, the Nook, which hasn't even hit stores yet, is in pre-order nirvana right now. The first run for the Nook occurred at the end of October (the product was introduced on October 20). These buyers were told the reader would ship on November 30. High demand resulted in backorders, so the next wave of pre-orders was scheduled to ship on December 7. Now, a third group will have to wait until December 11.

This product is on fire, and it still isn't even on shelves yet.

Mary Ellen Keating, a spokeswoman for Barnes & Noble wouldn't reveal how many of these devices have been pre-ordered, but she did say, "Demand for the product in our stores and online has surpassed our expectations." She also noted, "We are working hard to meet demand for the holidays."
