Don't really care so much about total post count, as it can be skewed. Could have some marketing value vis-a-vis advertising for the site owner, but not that important to me.

However, what I do occasionally look at is average posts-per-day. When I see someone with what in my view is an overly high PPD, I wonder how much travelling they can really be doing if they have the time to be on FT so much.

Sort of creates its own filter, doesn't it....
