An interesting piece of legislation is now blasting its way through the chambers of the Maryland legislature. This legislation threatens to lay waste to Internet social networking as we know it, if not for the inclusion of one solitary line of text.

While it appears honorable and well-intentioned on it's face, Maryland's HB65 (pdf file) is meant to place severe restrictions on the practice of international marriage brokering. If signed into law, the bill will place strict and deeply invasive disclosure requirements on the clients and providers of international match making services. This legislation does not bode well for the likes of eHarmony and Match.com.

Are you still suspicious of the $6.5 billion Facebook valuation that resulted from Digital Sky's $100 million investment last July? And doubtless, the $15 billion valuation implied by Microsoft's (MSFT) 2007 investment in the company was, to say the least, aspirational. Well, the insanity is continuing to mount – throughout the Facebook ecosystem. A recent report by Global Silicon Valley Partner's NeXt Up Research organization puts the price tag of Zinga, the Facebook application developer, at a whopping $3.3 billion ... half of Facebook's!

Granted, Zynga has done a few things to wow social media market-wachers and investors. NeXt Up Research forecasts 35% growth for this company over the next four years and just upped its 2014 revenue projection to $1.1 billion. The previous estimate was only $460 million. What could possibly justify these numbers? Well, Zynga has grown from 30 million users to 230 million in only 10 months, largely as a result of the strength shown by Facebook over this period. Farmville has been the company's engine, with close to 80 million monthly active users.

Facebook is becoming a powerful force in the search engine market. It's still far behind search behemoth Google (GOOG), but the social media platform's U.S. search traffic ticked higher by 13% last month, according to data from comSore (SCOR). From 351 million search queries executed on Facebook in December, the number grew to 395 million in January.

Google still owns 65.4% of the U.S. search market, having received 14 billion search queries last month. Yahoo! (YHOO), Microsoft (MSFT), Aol (AOL) and Ask share the remainder of the market. Among these competitors, market share changed little month-over-month. So, for Facebook, this month's growth bucked the trend.

The December 2009 data from comScore (SCOR) were released Tuesday, and the results for the social media sector are nothing short of staggering. Fifty-four percent (112 million) of the 205 million-strong U.S. internet-user population are on Facebook, with 27% (57 million) still using News Corp.'s (NWS) MySpace. But according to data from both comScore and Experian Hitwise (EXPN), the most active users were on Tagged, MyYearbook and Orkut. And Facebook users were more active than those on MySpace.

There's no doubt that plenty is happening in the social media space, but there are some facts that just might surprise you, either because of the speed of change or the discovery of players that may not have occurred to you.

You'd think retailers would flock to any place where they could find 400 million people. With the sixth anniversary of Facebook closing in, its robust user base still hasn't opened the eyes of many retailers.

Despite all the Black Friday social media engagement this year, a substantial 75% of the top 100 online retailers don't have a formal presence on Facebook, according to a study by ForeSee Results. Another 25% haven't even hit 10,000 fans.

Google (GOOG) is accustomed to being in the top spot. It leads search and virtually owns the online ad space. Its Google News portal is among the top sites for directing traffic to media outlets. But, the behemoth is starting to feel the feet from social media sensation Facebook.

Not only is the rather young platform stealing market share from Google News, it's now encroaching on its e-mail turf ... a situation that Google isn't taking lightly. To compete more effectively with Facebook, Google is upgrading its Gmail capabilities to include more social media tools reminiscent of those found on its competitor.

How are readers finding the news? Well, increasingly, the answer is Facebook. The social networking site, which boasts well over 350 million registered users, is now the fourth largest referral source of traffic to online news destinations. Almost a year ago, only 0.5% of traffic to news and media sites came from Facebook. Today, that level is 3.5%, according to data from Web analytics firm Experian Hitwise.

Only Google (GOOG), Yahoo! (YHOO) and MSN (MSFT) send more traffic to news sites. Google News, a subset of the search engine giant, failed to keep pace with Facebook, despite the fact that it exists specifically to send Internet users to media outlets. Only 1.39% of referrals came from this source.

The three major social media sites have been pushing new tools out to their user communities aggressively over the past year. Each company has its own set of rumors, from IPOs to being on both sides of an acquisition. While the ultimate 2010 aims of Facebook, Twitter and LinkedIn may not have been revealed to us yet, it is clear that all three are looking for ways to beef up revenue and demonstrate long-term viability.

Whether or not Facebook goes public this year, it's still pointed toward that ultimate goal. The 350-million member social network is focused on finding new sources of revenue and gaining better penetration into those it already has. Even if it's more than a year away, it's never too soon to start shoring up your financial statements for an IPO. The latest new feature from Facebook, which has been announcing enhancements fairly rapidly over the past few months, is targeted directly at advertisers, underscoring the importance that the company's attaching to revenue growth.

Facebook was busy on Christmas Eve and Christmas Day, according to Hitwise, but people weren't playing online games. It seems they were more focused on staying in touch and spreading the usual holiday cheer than tending to their farms, cafes and organized crime battles.

Over the holidays, Facebook was the top Website visited in the U.S., Hitwise reported via its Twitter account. The Web metrics company tweeted the bold statement: "Facebook was the most visited site in the US on Christmas Eve and Christmas Day. 1st time the site has been the #1 visited US site ever."

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.

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.

Although I have a couple of different topics concerning the life of someone who travels frequently for work that I wanted to write about this week, my mind and heart are filled with thoughts and concerns for a good friend and his new baby girl. I've been waiting for weeks to get a status on his new baby girl, and this morning I heard that since her birth Monday night, she's been in the intensive care unit. As soon as I read the update, my heart began to ache, and my eyes started to tear. Now, I'm not the most sensitive person in the world, but the thought of my friend's baby girl struggling for her life just rips me apart.

Throughout our travels, we get the opportunity to meet more people than imaginable. Some people we would love to call a friend and see every day, and some we hope to never see again! Years ago (not that many years), it was easy to travel, work with customers or vendors, and bid farewell, never to see them again. However, in the days of LinkedIn and Facebook, the ability to maintain contact with a one-time introduction becomes as easy as catching up on the day's news.

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.

Company attitudes toward social media sites vary. Some swing the doors wide open, allowing employees to tend to their Facebook farms and update Twitter statuses throughout the day. Others lock 'em down, keeping non-business site access to a minimum.

A recent study found that, in the United States, 77% of employees with Facebook accounts check in with the community from the office. And, the amount of time they're spending in this part of the online world is growing. In the United Kingdom, another study found that 57% log in regularly from work, costing their employers 40 minutes a day.

Philip Wicks, a consultant at Morse PLC, a technology research firm in London, "It isn't just something you can do for half an hour during a lunch break but all through the day and because of that, it has a huge impact because people aren't necessarily concentrating on what they should be doing during the day." He estimates that this translates to lost productivity of $2.25 billion a year.

It seems like the obvious move would be to block the sites, but William Beers of PricewaterhouseCoopers disagrees. "Instead of trying to shut it down, I think we should try to embrace these technologies, put in a nice policy that governs it and explain to users the risks related to it, provide some training and then see what business benefits we can have from it," he said.
