I'm not so sure about the "must-comment" (sometimes you don't have anything to say) and I don't agree with the auto-scroll at all.

Every user can decide how to read a post and how fast do so. That's their choice, you can't force them to read at a decided speed. It's okay to force to OPEN the article, but it's not ok if you try to force them to read it entirely at a precise speed. Nonsense.

The fees could also be arguable. Is it really necessary? I think we can find other way other than "typical" way.

For the rest, I agree pretty much on everything, even if I have some little arguments on some of the proposals. Anyway, keep posting! I love seeing new ideas!
