A recent post on Elise.com shows some interesting market share information about different blogging tools. The post shows that SixApart, between TypePad and LiveJournal, owns the market right now, though, each of those tools has a smaller market share individually than Blogger. Of interest to me as a longtime Manila user is the market map of Google Share vs. 6 mo growth rate, which shows that the number of pages on Manila appears to be shrinking (probably due to the shutdown of EditThisPage.com), while the number of pages on Radio blogs is growing at about a third the rate of speed of the overall growth of the blogosphere.
An interesting contender that emerges from that market map is b2evolution, which had the fastest growth rate but the smallest Google share.
Of course the usual quibbles about methodology apply, including the fact that many sites run by standalone software installations or using custom templates don’t point to their blog tool on their template. Like this one, for example, though I’m about to fix that.
