Blogum is a beautiful grid based WordPress theme from WP Shower. It has a minimalistic design which is perfect for those of you who want to put an emphasis on content.
As will all with WP Shower designs, the theme is well coded and easy to modify. It works with all new WordPress 3.0 features, beautiful typography and a discreet sharing link for sharing posts via Facebook, Twitter etc.
Blogum is free to download. It works right out the box though it would also serve as a good base for building your own design.
