I think the biggest problem I have is clicking or the wrong link because some banner thing finally loaded at the top of the page and pushed everything down. (I don't have great internet at home.) It drives me crazy, because then I have to back up and wait for the page to reload again.

Another tip for helping people with slow internet: don't break your article into multiple pages! I think the primary reason for doing this to get more ad traffic, but I promise I will leave when I see that your list of ten items is separated into ten pages.
