I'm a regular WordPress user and hopeful Codex contributor. I currently run the following websites using WordPress 1.5:

Distro Jockey - A guide to new Linux users trying out the many flavors of Linux

CoderBlog - Where Danger gets to rave about WordPress

Election Result 2008 - A watch on the contenders for 2008

DVDMP3 - All about multimedia conversion

Gasoline - Gasoline and gas prices (news)

Cheap Laptop - My hunt for a good, cheap laptop

Danger Stevens - My personal site

I'm working on a plugin that tracks user clicks on a page and keeps them in a database. I'll keep y'all posted on how that turns out.
