As another OD male here, I can safely claim to be one of the people who has many regular readers with my "I had a good day" entries. It's all in the quality of writing, the sense of humor, just like E2.

OD has a viral effect which is fascinating to watch because you know (in the anonymous sense) who is leaving you notes. You can click through their name and start reading their diary, and then click through the people who read their diary. Pretty soon the people reading their diary are also reading your diary, and it becomes a big Ponzi scheme.

This becomes especially outrageous if, like me, you have someone from the real world find and read your diary, and then they start their own diary, about you.
