I futzed around with this idea for a bit using php bloxsom, and well, I got it to handle markdown the way I want it to, and the page header stuff. but other than that. not so much. sigh. well what's time anyway.
I think the problem with this is that bloxsom is too blog-oriented, and for that, wordpress does a slightly better job, or at least, I'm more comfortable with it, even if I don't need very many of the features.
Though I have to say, for the notebook idea, which is what tychoish is supposed to be, I think bloxosm is better, I just don't feel like fucking around with it.
anyone with better ideas?
