Whilst it's hard to envisage anybody stealing MySpace's crown, Friendster, which pre-MySpace was dominant, now has a measly 0.34% share — reminding us that MySpace's pole position is their's to lose.
The fastest movers and shakers were both social networking sites that specialize in building communities around music and other media — Buzznet (up 148.4%) and iMeem (up 145.7%). Other fast growing sites include Hoverspot (up 19.6%) and Bebo (up 17.8%), which both compete more directly with MySpace.
