I agree with gcatalfamo, while infinite scrolling websites seem like, "hey that's cool, I want to be with the in design crowd" they are actually pretty heinous for all the reasons mentioned above. I want a scroll bar that reflects were I actually stand with info contained on the page, not the content that is currently on that page. Refreshs and navigation don't bring you back to where you were. I just think they are obnoxious. I'd rather page through results and be able to predictably get the results from those operations that I expect. Just say NO to infinite scroll!
Infinite scrolling usually is usually time ordered data. If you could type a link with an arbitrary date and time and it took you to the right place, then that might help slightly and would not be that hard to set up. The problem with infinite scroll is it needs extra elements to make it nice, not that it is evil in and of itself.
