What were the top social media sites of 2008? ComScore came out with its worldwide traffic stats for November a few days ago (so these don’t include December). They are a mix of social networks and blogging platforms. Blogger, the orange line in the chart above, still rules the roost with an estimated 222 million unique worldwide visitors in November (up 44 percent from November, 2007). Facebook, the blue line, is on pace to pass it soon with 200 million unique visitors (up 116 percent). (Note, though, that this is more than the 140 million active users Facebook itself reports—go figure). MySpace is pretty steady at 126 million uniques. WordPress is a close fourth and gaining with 114 million (up 68 percent). And Windows Live Spaces is down 22 percent to 87 million uniques.
