Guilty.

One of the things that got me into Perl was Ward Cunningham's original Wiki server, which was a single Perl CGI written in a semi-literate fashion (it bootstrapped itself from a set of Wiki pages). I thought Wiki was way cool (this was '95, and it was still way new), and grabbed the source for study. It proved not to be the world's best Perl, and I submitted several fixes, and later some extensions. That got me hooked. I've since written my own Wiki (and have replaced the codebase twice), and my own blogging software (twice). I think that particular set of itches is well-scratched now. Perl made the scratching easy.

But, time goes on, and eventually I realized that it was easier to let other people maintain stuff, so I switched to MoveableType. I'm now considering switching over to Bloxsom, for more fine-grained control.
