If Mark Zuckerberg knew then what he knows now ... Facebook would be more like MySpace, which is now owned by News Corp. (NWS). And, he's willing to admit this in public.

In a six-minute on-stage interview with TechCrunch, Zuckerberg went on at length about the social media platform's privacy settings, which have been the subject of unending debate. He says that he'd make more data public by default if he could start Facebook again. Though Zuckerberg cites Internet trends that indicate a reduced concern with privacy, the real reasons are more likely financial.

Facebook could use more older women, not to mention younger people in general. As the company pushes toward what is expected to be an IPO in 2010, it needs to shore up its user base in all demographics, if for no other reason than to diversify against a new social media platform that appeals to a specific community. So, even with the site pushing past 100 million monthly active users according to its advertising tool, with the addition of 5 million in December, there is work to be done if Facebook will make a successful entry into the public market.

Long derided by "serious folk" as a place for kids, Facebook's membership consists mostly of adults. Fifty-six percent of the user base is female, and 60% of users are 25 years of age or above. In fact, 20% of them are at least 45 years old. Some of the groups that are underrepresented are showing rapid growth. Men over 55 grew twice as fast as their female counterparts, though the younger generation moved onto Facebook most aggressively last year. Users age 26 to 34 showed the biggest overall increase in 2009, with 839,000 monthly active users. This represents a substantial shift from the trend earlier in the year, in which it was the later generation flocking to Facebook. Women over 55 didn't jump on the bandwagon as quickly as other groups.

Revenue hasn't been as fast to change as end-user sentiment, but all that looks like it's coming to an end next year. Social networking site Facebook, which passed 350 million users last month, is poised to move ahead of rival MySpace in ad revenue in 2010, according to a report from eMarketer. The research firm expects Facebook to rake in $605 million in ad spend next year, compared to $385 million for MySpace, which is a News Corp. (NWS) property.

According to Debra Aho Williamson, senior analyst at eMarketer and author of Social Network Ad Spending: 2010 Outlook, "As more marketers incorporate social networks in their business, they will no longer look at them as siloed destinations. Instead, they will look to increase the impact of their social network presence by linking it to other marketing initiatives, both online and offline."

Does anyone remember Friendster? For about ten minutes seven years ago, it was the hottest thing in social networking. The site that effectively kicked off the social media movement didn't stay in vogue long, however, eventually riding a wave of user referrals to Asia. Meanwhile, MySpace, Facebook and Twitter came along, taking over the sector -- and the hype that comes with it.

Well, Friendster is worth something to somebody, it seems. The company is due to be sold at the end of the month for $100 million. The social networking service is tops in Asia, which is where more than half of its 100 million-strong user base can be found.

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.

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.

Who needs venture capital money when you have litigation? Facebook was awarded $711 million in damages Thursday in an anti-spam case against Sanford Wallace, an internet marketer. The popular social networking platform went after Wallace for tapping its users' accounts without their permission and sending fake posts and messages.

Wallace has quite a reputation for spamming, having gained the nicknames "Spam King" and "Spamford" back in the 1990s, when he was good for up to 30 million spam e-mails a day.

Google (NASDAQ: GOOG) makes it easier to search for websites, e-mail messages, passages from books and videos. Where you haven't heard much about Google's search capabilities -- or Google in general -- is the music business.

But, that's about to change. On Wednesday, the search giant announced that it was partnering with music services such as Pandora, Lala, News Corp's (NASDAQ: NWS) MySpace, and Rhapsody by RealNetworks (NASDAQ: RNWK) to help users find, listen to and ultimately buy music on the web.

Your e-mail account is a goldmine. Technology companies push hard to keep your data secure, but there are plenty of scumbags out there who always seem to find a new way to gain an edge over the guys in white hats. Phishers, in particular, are eager to find new ways to profit from your identity and information, and they're getting some new tricks.

Phishing scam activity was quiet at the beginning of this year, according to a report in USA Today, but these attacks surged 200% from May through September, says the X-Force team at IBM (NYSE: IBM). Webmail, social media and gaming accounts are their primary targets. E-mail access, in particular, is highly sought after, since they can be use to push out spam ... while bypassing filters.

These "virgin" e-mail accounts command top dollar: a digital criminal can pick up as much as $2 for a clean account from Microsoft (NASDAQ: MSFT) Windows Live, Google (NASDAQ: GOOG) Gmail, Yahoo (NASDAQ: YHOO) YahooMail or AOL (NYSE: TWX). This is more than twice the amount typically paid for a stolen credit card account, according to Fred Rica, principal in the security practice at PricewaterhouseCoopers. Many webmail users actually do half the criminals' job for them, with 33% using just one password online and 48% using only a handful.

It was still a good idea for News Corp. (NASDAQ: NWS) to buy MySpace.com over fours years ago for a little more than half a billion. The social media network still brings in decent ad revenues, even though it is out of the popular fad culture of social media. That space is now owned by Facebook and Twitter. But then MySpace CEO Owen Van Natta says that his company is "fundamentally different" than Facebook -- as in a special experience providing entertainment content -- those words could come back to haunt him.

As will words like "I really don't view Facebook as a competitor." While it's true that Facebook and MySpace go after two types of online social interaction, they are both vying for many of the same customers in a large crossover audience. Teens, 20-somethings, and others are very fickle and many use both social networks. The two may have different goals, but they are competitors.

A new executive team is trying to bring MySpace back to its former glory. By focusing on music, videos and games, it hopes to recapture some of its luster. With the MySpace refugees mounting, it's time for some new blood to make some brilliant, future-changing decisions. This week, the company is holding a conference for its global ad sales team to explore ways to bring in traffic and beef up ad spending.

MySpace is poised to haul in $495 million in ad revenue this year, down 15% from last year's $585 million, according to research firm eMarketer. In August, MySpace attracted 64.2 million unique visitors from the United States, off 15% from August 2008, according to comScore, while Facebook pulled in 92.2 million unique U.S. visitors – up more than 100% year-over-year.

Have you ever looked at your Yahoo! (NASDAQ: YHOO) Flickr account and thought, "Why am I doing this? I can just throw my pics up on Facebook"? If this has crossed your mind, you're not alone. In fact, many photo-sharing sites – Snapfish (NYSE: HPQ), Photobucket, Picasa (NASDAQ: GOOG) and Shutterfly, as well as Flickr – are asking the same questions. With the development and enhancement of photo management capabilities in major social networking websites, niche players need to find new ways to stay relevant.

The situation is still far from grim. Fed by traffic from their behemoth owners, the photo-sharing sites remain substantial forces, and they are currently home to more than 20 billion pictures. There's still plenty of interest in these environments ... which has been bolstered by specific features that make the likes of Flickr attractive to both professional photographers and amateur shooters. The ability to order prints and personalize portfolios, for example, still provides an edge over sites like Facebook and MySpace (NYSE: NEWS).

Nonetheless, the threats from the social networking space are quite real.

As expected, today MySpace -- which is wholly owned by News Corp. (NYSE: NWS) -- has agreed to purchase iLike. The terms of the deal were not disclosed (although, the buzz is that the deal came to roughly $20 million).

Tech veterans (and brothers) Ali and Hadi Partovi started iLike back in 2006 (I actually had a chance to talk to them back then). The goal was to create a social music discovery site, leveraging emerging platforms like Facebook, Orkut, hi5 and Bebo. In fact, iLike was able to attract more than 50 million registered users.

While impressive, there were some problems. First, a big chunk of the traffic came from Facebook. So, the concern has always been: what if Facebook wants to compete in the space?

News Corp. (NASDAQ: NWS), a media company that competes with Disney (NYSE: DIS), General Electric's (NYSE: GE) NBC Universal, Sony (NYSE: SNE), CBS (NYSE: CBS), Time Warner (NYSE: TWX), and Viacom (NYSE: VIA), reported Q4 earnings on Wednesday after the bell. They were unimpressive. Revenues decreased almost 11%. On a reported basis, the company lost 8 cents per share, compared to a profit of 43 cents per share in the year-ago period. That is a depressing drop, but on an adjusted basis, News Corp. made 19 cents per share, which, according to Bloomberg, was a single penny ahead of expectations.

The company's problems with MySpace always make the news these days. Technically, the site is a part of Fox Interactive Media, and it is that division of NWS which took on charges that helped to drive the GAAP loss. Remember when MySpace was so important to shareholder value? Not any more. Facebook and Twitter have now taken all the buzz, and News Corp. just isn't having a fun time with this investment. This is one area that management obviously has to work on.

While MySpace still has an enviable user base, the future is looking dicey. Facebook continues to grow at a relentless pace -- and appears to be the de facto social network. There is also the sudden emergence of Twitter (which, by the way, is even putting pressure on Facebook).

To deal with this, MySpace's owner, News Corp (NYSE: NWS), is taking action. Just last week, the company slashed about 30% of the U.S. workforce.

As for this week, about two-thirds of the global work force will be fired, going from 450 to 150 employees.
