Of course the Internet will be taxed. The Web is packed with opinions on good and bad navigation, along with many pages of guidelines on how to get it right. But let's skip all that and look at one or two original concepts based on the way your visitors think. The first of these is whether navigation links should be at the top or bottom of a page. But for longer pages it becomes important because of scrolling.
Nobody likes to scroll.
We're all lazy and when we're ready to move on to another page we want to see the link right in front of us. If they're looking for links at the top of a page, then they've probably not read it. I'm not interested in this page. I want to go somewhere else. If they're looking for links at the bottom of a page, then they've probably absorbed at least some of it.
