He notes the increase of Wordpress, but doesn't attribute a reason: "The most interesting change I see is the increased use of WordPress, which has increased (as a percentage of new blogs added) almost tenfold since last year."
One reason, in my opinion, may have been the Blogger fiasco of last year where thousands of blogs were marked falsely as spam and it took time to fix that major problem.
Tracing the Tribe set up a mirror site on Wordpress to enable continued reader access. When I posted about my solution; other geneabloggers followed suit.
Another reason may have been the recent Blogger-IE 6,7,8 problem in which readers using Internet Explorer had trouble viewing Blogger sites; the technical problem did not impact Wordpress blogs.
Once again, Tracing the Tribe reactivated its Wordpress site due to this problem.
