switching to wordpress was the best move I’ve made for my blog. Everything is so simple, and there are tons of themes and plugins available (also usually extrememly easy to install). Speaking of themes, there is a MONSTER list of free themes available at http://www.emilyrobbins.com/how-to-blog/comprehensive-list-of-615-free-wordpress-15-and-20-themes-templates-available-for-download-266.htm…no screenshots though, just links. There’s a bunch of other theme viewers out there which do have screenshots, but the list at emily robbins has a nice selection, looks pretty up to date, and has good info as far as what each theme supports.
