OK, here are 2 blogs I love:
Postsecret is a fantastic idea - it's a project where people send in anonymous postcards sharing secrets they haven't told anyone else. Some seem so freaky, you almost wonder if they are real!
Chromasia is a wonderful photo blog. The pictures are breathtaking, and if you read the comments, you will get more details about the exposure, film, etc.
But my favorite site is ...
PhD Comics is a fantastic (make that FANTASTIC!) comic strip by a talented bunch at Stanford, and is a hilarious (and sometimes dangerously accurate) account of graduate school! OK, if you were thinking of coming to grad school, please do not visit this site!!
