Here is a great 3 part series from a new blog I discovered called SolutionWatch.
Part 1 is awesome because of the list of cool online web tools for students. The list has some that I already know of, but MANY that are new to me.
My personal favorite is very low tech The PocketMod. But I LOVE IT! I really love my Treo, and my iMac, and my digital camera and my digital video camera, but as hard as I try to go paperless, I just can't make it happen. I ALWAYS end up with paper. So I don't fight it any more. Instead of carrying a bulky note pad and pen in my pocket, I can customize a little booklet from one well designed 8.5x11 sheet of paper.
Much like MOO.com, this is simply beatiful design because its easy and helpful.
