29 social networks that have at least 1M visitors per day

Facebook has stated that about half of its users log in to the site every day, which seems to match these numbers.
It’s interesting that Orkut, counted out by many, clocks in a significant number of daily visitors. From this perspective, it’s the second-largest social network in the world. This is in large part due to it’s extremely strong following in Brazil and to a somewhat lesser extent, India.
How the mighty have fallen. MySpace is only number 12 on this list. (And speaking of the fallen, Friendster didn’t even make the list.)
Facebook dominates to an almost ridiculous extent. Combine all the daily visitors for the other 28 social networks on this list and you still only end up with two-thirds of what Facebook has.
