Jacob complains about the complex file and directory structure of Habari. I've hacked the core, worked on themes and plugins, from scratch and extending others, of both WordPress and Habari. I've done a fair bit of coding over the years, but I certainly wouldn't call myself an expert. All that said, and not wanting to denigrate WordPress, there are two things that stand out for me that make Habari very attractive. First, writing themes and plugins, even in this very early stage of development, is a joy. I find things "just work" often. To me, that structure makes that hacking a lot simpler. Second, the community is simply awesome. The energy, inventiveness and support that's been flying around just in the last couple of months has been a joy to behold.
Frankly, I don't care what's happening on other projects. I'm just enjoying working on this one, even in a very minor way.
(I do think Habari could use some more tests. I don't have much experience with testing, but if someone sets up the framework and a couple of examples, I'll certainly add a bunch of tests.)
