Re: hybrid pagination, I like the idea - but that particular implementation was a little wonky for me. Since the reading area was taller than my browser window, so I scrolled down to read the whole "page" and then had to scroll back up to continue reading. And since it seems to scroll based on scroll events from the browser, I wound up scrolling back to the first "page" in the article while trying to do that and the whole thing winds up being kind of a bummer.

I think a potentially nice implementation of this idea would be more like reading on a Kindle - text is broken into screen-sized chunks, and then there are low friction ways to go forward and backward "chunks".
