The blogosphere simply loves to slurp up social-networking traffic stats, and on Monday we got a nice tasty serving of them with some new numbers from Compete.com for the month of January. The results? Facebook is in the lead, with about 68 million unique visitors, well ahead of MySpace’s 58 million. (The two are pegged at 1.1 billion and 810 million page views, respectively.)

This may be the first survey we’ve seen that puts Facebook ahead of the News Corp.-owned MySpace in U.S. traffic. It also puts Twitter as the third-biggest social-media site in the country by total page views, with only about six million unique visitors but a whopping 54 million views.

Compete’s numbers are interesting, because they often are pretty different from other analytics firms’. Here are some clarifications, explained to CNET News in an e-mail sent by Compete’s Andy Kazeniac: These are numbers stemming entirely from Web browser data in the U.S. That means that you won’t be pulling in any international numbers, where most of Facebook’s users are now, or data from widgets or third-party applications, which are how many avid Twitter users access the service. That means that it’s likely that Twitter’s reach is bigger than the numbers indicate.

What’s also intriguing is that there are a few social-media sites, like Flixster and LiveJournal, with relatively low unique visitor counts but proportionally very high page view counts, indicating that they probably have smallish bases of very loyal users.

Also pulling in notable numbers are LinkedIn, with about 11 million unique users, Classmates.com, with about 17 million, and Reunion.com, with slightly under 14 million. On the other end? AOL’s Bebo, an $850 million purchase, which Compete.com clocks in as having just shy of three million unique visitors. True, its biggest user bases are in the U.K. and Ireland, but that’s not good considering the price tag.

Still, statistics are like tequila shots. Always take ‘em with a few grains of salt and a slice of lime, and be warned that they may give you headaches.

WASHINGTON — There is one addiction President Obama will not have to kick: his BlackBerry.

For more than two months, Mr. Obama has been waging a vigorous battle with his handlers to keep his BlackBerry, which like millions of other Americans he has relied upon for years to stay connected with friends and advisers. (And, of course, to get Chicago White Sox scores.)

He won the fight, aides disclosed Thursday, but the privilege of becoming the nation’s first e-mailing president comes with a specific set of rules.

“The president has a BlackBerry through a compromise that allows him to stay in touch with senior staff and a small group of personal friends,†said Robert Gibbs, his spokesman, “in a way that use will be limited and that the security is enhanced to ensure his ability to communicate.â€

First, only a select circle of people will have his address, creating a true hierarchy for who makes the cut and who does not.

Second, anyone placed on the A-list to receive his e-mail address must first receive a briefing from the White House counsel’s office.

Third, messages from the president will be designed so they cannot be forwarded.

The battle over whether the president could keep his BlackBerry has been fueled to a large degree by Mr. Obama himself, who mentioned it again and again. He would not take no for an answer. In an interview this month, he worried aloud, “They’re going to pry it out of my hands.â€

Mr. Obama received his BlackBerry on Tuesday, but officials declined to specify what kind. In a conversation with reporters on Thursday evening, he said, “I don’t think it’s actually up and running yet.â€

Putting your thoughts in 140 characters and sharing them with the world is shaping up to be more popular than “digging” your favorite news. According to new market share numbers from Hitwise, Twitter, the popular microblogging service, is now more popular than Digg’s social news aggregation service. Hitwise compared both sites in a report released Tuesday and is basing the market share ranking by page views.

Unfortunate events such as the Hudson River plane crash and also more fortunate ones like Obama’s Inauguration, led to more mainstream exposure for Twitter and moved it above one notch above Digg in Hitwise’s hierarchy – Twitter is now ranked at 84, with Digg at 85.

When the US Airways Flight crashed into the Hudson River late last week, the first reports of the incident appeared on Twitter, including amateur photographs that later made headlines around the world and transformed Janis Krums into a celebrity of the moment. Hitwise confirmed the fact that this event was one of the main factors of Twitter surpassing Digg in visits market share.
