This is entirely untrue I can still use my scrollbar to get back to the top of the page again, it can also be used to easily skim the results that were displayed.

Pop quiz: according to convention, while using your scrollbar to skim the results that are displayed, what position do you move the scrollbar to (or avoid moving it to) in order to trigger (or avoid triggering) loading the next chunk of content? Hint: it's not the bottom.
