Microsoft’s blogging service has grown from an estimaited 18 million blogs in October to 27 million blogs and at least 7.6 million active bloggers, according to Dare Obasanjo from Microsoft in a post discussing server issues.
The service still remains in third position amongst blog providers, with Xanga and MySpace both believed to be hosting 40 million blogs each.
(note: calculations based on this line: “I never expected [Spaces] that we’d grow to be three times as big [as Live Journal] and three times as active within a year.)
