100 Comments in 100 hours
At last check, he still has 18 to go, but he's getting there. The guidelines he's going to follow:
1. The total number of comments submitted in 100 hours must be at least 100.
I'm glad to say that I was part of this project, as comment number 55 (which is the only reason I knew about this project).
2. Comments must be on topic (I'm not trying to contribute to webspam) [...].
3. Comments submitted to sites on a blogroll or regularly read bloglist do not count toward the 100.
4. Neither do multiple comments on one weblog.
5. Linking/Trackbacking ties it all together.
