I'm curious how seamless that implementation was. I've seen a few hacks that load-then-scroll which is, of course, just about the worst of all worlds.

IIRC we ended up using a cookie (in non web history api browsers) so when you hit back the page would render the entire necessary result set to get you back where you were. Ie, no Ajax load to wait for. (Don't quote me on this :))
