What I hate the most is when I'm using a scrollbar and the infinite scroll adds more content to the bottom of the page and suddenly the scrollbar jerks up because I'm now 30% down the page instead of 15% down the page--then it takes me a minute to find where I was before the infinite scroll event. Happens to me ALL THE TIME. F-ing annoying. A "load more" button with some kind of ---------next page--------- line to delineate the new content would be preferable. The solution is to use the "Page Down" key but that's not always intuitive.
