It might be worth looking at http://www.khanacademy.org/ for an effort in web learning. At this point it's mostly short youtube videos (quite a few of them) concentrating on one concept spanning math, physics, economics and some others. You can also create an account and get a personal "map" to see how you are progressing (were you go from basic concepts, and then build from them). The guy in charge wants to have videos about every possible subject and have one such knowledge map for them. Eventually, I think he also wants to be able to have online tutors helping individual students in the future. I realize my explanation probably doesn't do it any justice so I instead refer you to http://www.youtube.com/user/khanacademy (the video in there) which should give a better overview of it all. There is also a longer video somewhere that has even more details.

I just thought I would share, maybe someone here will like it or find it useful.
