Sometimes it's overly "heady", but I like how Michael Bierut, William Drenttel and Jessica Helfand have created a really solid community focused on good design criticism.

I won Michael's books, this is the best design blog because i think there perspective is the best i take the most out of this blog.

It's a whole lot deeper than other design sites and blogs. If you feel like really understanding design perspectives, read some of their lengthy essays. Not just a gallery! A thinking exercise!
