Why are you writing your own blog script? Why not just stick with Wordpress?
I love WordPress, don't get me wrong. The thing is though that it's kind of bloated... It's full of needless JavaScript and AJAX stuff that I never use. I don't use the themes either, so they're just another bunch of (empty) redundant folders on my server.
Plus, WP's security has been debated recently.
I'm writing my own because I want to, because I want a challenge. I may or may not end up using it - it depends if a) I can finish it, and b) if I can make it work properly. At the moment, its functionality sort of resembles that of WP, but without the JS and without the bloat that I don't need.
