I'm surprised at how many people here seem to like infinite scroll. I personally can't stand it. Imagine having a book where no matter how much you read, it never seems to end. No milestones, no sense of progress. Just page after page after page. It just feels... icky.
It's worse than that. At least with the book you get to turn the page. This is more like having a book, and knowing there's other pages, but you can never get to the bottom of the page you're on.
Meanwhile all the stuff you have already read is sitting around in a big mess, doing nothing but taking up space and getting in the way.
