I can't take credit for these, but I still think they are rather interesting. Both are located on blogspot, but neither are your typical blogs.
The first is called PostSecret. The premise is simple: people anonymously share their secrets by sending postcards to this guy in Maryland. Then he scans them and posts them. Quite interesting and provocative.
The second is Ask a Ninja. I'm just starting to look at this one, but I think it works like this: people email the ninja with questions, then he does a video repsonse. Some of the videos are re-done by viewers and are quite funny.
