To be honest, logistically it might be easier to do top
posters of the year. Trying to find and evaluate each individual post would take forever, and since Ferd's job tightened up on him, nobody has that kind of idle time.
Perhaps it would be easier to look at individual posters and the totality of their posts in quality, content, and spirit.
There are several that I would nominate as top ten. Maybe we could also consider a Razzies option for the ten worst posters of the year.
