One of Smashing Magazine’s first and most well received posts was a sort of WordPress theme gallery, similar to the galleries I manage and update here at Hack WordPress. Now it looks like they’ve gone back to their roots with another post dedicated to WordPress themes.
This post is titled 100 Excellent Free WordPress themes, and it doesn’t disappoint! There are a number of really incredible themes here, including a few that I hadn’t run across yet. This weekend I plan to go through their post and update the appropriate galleries here on this site. In the meantime, I recommend you click over and check it out!
