Reason behind the rhyme

MySpace.com again tops the rankings of top US social networking sites, with nearly 57.4 million unique visitors in November, down from October's 58.8 million, according to custom lists of top US social networking sites and blogs compiled by Nielsen Online, reports MarketingCharts.

Google's Blogger rests atop blog site rankings with 33.6 million visitors, down from October's 34.1 million.

Ranked second among social-networking sites, Facebook increased the number of visitors to nearly 22.0 million, up from October's 19.5 million — and up 89 percent vs. Nov. 2006, whereas MySpace visitors increased just 7 percent year over year.

(Compare with Oct. social-network data.)

Among blog sites, top-ranked Blogger increased its visitors a significant 49 percent from the year-earlier period, accounting for 33.6 million visitors in Nov., albeit that was down from this October's 34.1 million.

More impressively, WordPress, which maintained the No. 2 rank it first achieved in Oct., grew 310 percent from the year-earlier period. In Nov. it accounted for 12.0 million visitors, up from 11.4 million in Oct. — and up from 2.9 million last year.

Six Apart's Type Pad, now No. 3, also grew — 22 percent from last year — to more than 11.0 million in Nov., up from nearly 10.6 million visitors in Oct.
