Top social network MySpace continued to hover around 60M, with an official count of 59.1M. If you’re looking for a shoe-in bet for your 2009 tech predictions, it’s this: Facebook will surpass MySpace in US traffic at some point next year. In all, Facebook has increased its traffic 116% so far this year, up from 21.9MM uniques at this time in 2007.
Elsewhere, Twitter grew nearly 50 percent month-over-month according to Nielsen, from 2.2 million unique visitors in October to 3.2M in November. That surge is likely due in-part to the US Presidential election, where Twitter played a big part in some mainstream media coverage.
Who are the other hot social networking sites as 2008 draws to a close? Tagged.com is up 465% since last year, Ning is +270%, LinkedIn is +114%, and Imeem is +68%. The full report from Nielsen Online is embedded below:
