In the case of my piercing diary I took the middle road, and offered an opt out (only taken up by one person). I still feel a little self conscious, but also self justify on the personal clinical interest front.

In general I think I tend to be more concerned with posting too often; I try to keep to at most one a day most of the time, but then wonder if 'that thing I was going to post about two days ago' is still relevant.

ObToenails: I need to keep mine well trimmed whenever I go dancing in the shoes pictured, or damage ensues. Also, one edge of each big-toenail (that next to the adjacent toe) has been folded over since some time in my late teens. There is indeed room on teh intarwebs for such observations, and my thanks for broaching the subject.
