Continuing the theme of linking blogs that are infinitely larger than this one will ever be, Twenty Sided is a blog run and maintained by Shamus Young. It focusses mainly on geek culture and general gaming and hardware. The main topic is essentially: What Shamus Thought Was Interesting, which is usually interesting at the least. He also posts a regular column on The Escapist, and has done several LP's of the Mass Effect series. Easily one of my personal favourite blogs, definitely worth a read.
