I promised myself I wouldn't, but I just did it anyway. I've written my own blogging engine, rather than sticking with the perfectly adequate and elegant bloxsom.
It's nothing fancy (not really an 'engine' at all), and I'm sure I'll get bored with it soon. I should probably concentrate on actually getting this stuff online somewhere, and maybe even thinking about some content.
Of course it's written in perl, and follows the bloxsom (static mode) model. In fact, it really just ties a bit of File::Find with Template Toolkit and some Image::Magick thrown in to make images a bit easier. It currently stands at ~360 lines, and I've only got 3 TODO items left. I might even 'publish' it when I've done those.
