UPDATE: I have since switched to WordPress due to spam issues. See my Battle of the Blogs: Part 2 entry.
This site is powered by b2evolution if you haven’t noticed. Why did I pick it? First of all, I searched on SourceForge.net on “php blog”, sorted by number of downloads and b2evolution came up at the top, with over 150k downloads. Now even though I have heard about WordPress before, it didn’t come up in the search. Even though they claim that they have moved off SourceForge.net, still a big mistake on their part to have neither “php” nor “blog” in their listing.
