i agree with rich, i'm really loving those badges i'm collecting there ;-) it's such a cute idea +1

Just chiming to add support for this, +1

i sort of agree, i like doctype's design a lot, but i also like that stackoverflow et al just seems to be a straight page of questions on the front. +1

i'm curious about the formula too. if i answer a question, i'm still on the front page even though someone after me answers. this is weird. +1

where i feel like this would be abused is if people turned their posts into comments in order to avoid downvoting. but i feel like this could be avoided if the points collected (or dropped) with the post could be separated from it somehow and kept part of the total rep pool. +1

I agree with the OP actually. It took me a while to figure out that everyone's icon was a gravatar and it should be pointed out on the profile page. +1

Yes i like the wiki and deletion ideas. Also, i wouldn't want there to be a time limit on deletion; people should full control over their own comments. +1
