Scrolling is a little too active now. The text doesn’t just move, there are also various colour changes, text appearing etc. A trifle disconcerting.
I think you could make it work better if you use CSS3 animations to make (some of) the other activities more discreet at first. For example, there’s a little button bar beneath the text of each posting. That could fade in, about 0.2s should be right.
The goal must be that when you’re looking at something, you see it without effort. But if you’re scrolling, nothing flickers and screams lookatmelookatme.
