There may be accusations of cliqueiness
It seems to me there are generally a few new or different names on the best of every week. Mind you I haven't been about long enough to judge properly.

There do seem to be a few people who almost always get into the best of, I agree with the results though, they are usually the funniest and best written that are voted best.

this is pretty much it
We've had a few people who obvious get upset if their post doesn't gain enough votes to make it to best of (Friz?) and who cry foul and suggest everyone's voting for their mates.

Spanky and Pooflake make it consistently because they're consistently funny. Chickenlady because she's consistently funny and well written. Chart Cat because he's a filthy, funny bastard!
