I complain regularly that I see so few blogs that aim to be art. It just seems like such an obvious thing to do with the blog format. I don't understand why there's not more experimentation out there, why artists aren't taking advantage of these free tools.
Occasionally of course, I find a gem.
New on my radar, PostSecret is an art blog that solely features scanned postcards received by the author. The idea is that anonymous contributors write secrets (anything they want, as long as it has never been disclosed) on postcards and mail them in to the creator of the project, who then makes them public using Blogger. The results are rich; sometimes funny, sometimes terrifying, every card dripping with honesty and relief. Visually impressive as well, the cards tend to take on a graphic quality, attractive to any student of typography, and familiar to any fan of mail art.
