Firebug

Dark yet colourful, the Firebug WordPress theme has two widget-ready sidebars, space allocated for ads and social tagging options built into the posts.

It’s also Gravatar ready, works with WordPress’s built-in Gallery feature and offers Photoshop file for replacing the logo in the banner.

Firebug has a stylish, modern layout. The background can make the (small) text a little hard to read, so a flat colour without the texture may be a better option.
