But why do we need the thumbs ratings at all?
Do we really need an approval rating poll on every post?
People can post an actual reply, which facillitates further discussion, and which is considerably more meaningful than an ambiguous thumb rating.
As you pointed out, posts are disappearing from.The Photo Association thread because of the intentional abuse of the thumbs ratings. Unless this sort of thing is stopped ASAP, this site will be completely trashed.
I am glad that Robert Gentel is addressing the problem in some way.
