tcervo.com is the first WP site I built. It used to be some static pages, with a home-brewed ColdFusion application for the Photo Album.
I created the blog portion of the site (to replace the static pages) back when Wp 0.72 was all the rage. I've customized and hacked (not always in the safest manner) so much that it's going to be difficult to upgrade to 1.x. I've got a local version running, and I'm slowly but surely fixing up all my changes.
Some of the "safe" hacks I've employed are the uber blockquotes hack, a stlightly modified nicer archives hack, and a random header graphic hack.
The site is a personal blog, and covers whatever I feel like blogging about at the moment: pop culture, web stuff, polictics, etc.
