TC: “Facebook’s growth keeps on amazing. In January this year, the official number of users was still 150 million, and grew to 175 million in February. That means that a stunning 50 million people signed up for the social network in 2009 alone to date (or 500,000 per day, more than the entire population of Luxembourg). – At the end of last month, we reported that its traffic is going through the roof too, particularly in the U.S., according to recent worldwide Comscore data. Comscore said more than 1 in 4 people with Internet access visited Facebook in February 2009, translated to 276 million monthly unique visitors (or more than twice the size of MySpace’s traffic).”
