Just wanted to let you know about the release of my new theme: Paperback.
The ethic behind this theme’s design is to do less, but do it better. By keeping things simple and eliminating clutter, Paperback is designed to get out of your way so you can do what you want to: publish well.
It's got semantic markup, fantastic typography and support for sidebar widgets.
It's released under the GNU GPL
You can find it here: http://gordonbrander.com/2007/11/17/paperback-theme-for-wordpress
Hope you like it, and let me know of any bugs on the post's comments.
