This is neat, but really disappointing that there is no feedback when you're at the top/bottom and try to scroll further. It'd be so natural to have this bouncy effect happen in-place to let you know you've reached the end.
"really disappointing" ?? another example of the HN changes around here.
What I say is that it's very disappointing that this demo goes 95% of the way to create something AWESOME, but those 5% it goes short are very stark and unfortunate. It's like a brand new Ferrari with a scratch. Wouldn't that be disappointing? Even though it's a Ferrari which is awesome.
The problem is that feelings are 95% positive and 5% negative, but my comment is 50/50. So it may seem that I'm being negative, when in fact I'm 95% positive. Hence those missing 5% are so disappointing.
Great job though, it's really neat (this goes without saying...).
Edit: The reason I talk about the negative is because it can be made better. I find it less useful to talk about positive because it's already good, so there's nothing to be done.
