Most of them are very good posters.
I think DanIronHamza should be on the list.
From the ones on the poll i really like Nchristos post 99% of the time.
(but I'm new around here and therefore my opinion may change when i dig deeper in the archives)
Anyway like someone said, I don't see the need for these popularity contests. It's quite easy to spot the good posters from the bad.
