To ehBeth, I'm starting to think that way too, at the same time I don't think it's best to change for other reasons having to do with the cumulative collection of ups and downs. But I think the thumbs graphics and big visible numbers do trigger or enhance "they don't like me" issues.
Anyway, we've talked about what is the default and I trust nimh's memory more than my own, that it is set at first to one of the thresholds. I think Craven said they're going to change that. (Don't trust me on what I think I saw.)
On the other hand, maybe there could be some explanation on the opening home page, and, secondly, this may change when there are "rooms" for categories like trivia and games.
