Redesigning The "Back" Button
TheMatt writes "Nature Science Update is reporting today about research by New Zealand scientists on redesigning how the "Back" button works in your browser.
They point to the fact that the current "Back" is more of an "Up" in a stack of pages. They propose a system that records all pages visited. A good summary page of their efforts in web navigation (including a interesting thumbnail-style "Back" menu) can be found on their page."
A 5 modded post on slashdot revealed a complete lack of knowledge about how the back button works. If you don't understand something, it will in general be harder to use. I think that this makes it a legitimate subject for research.
