Any websites that you like and find useful? Nothing too obvious of-course. I personally like websites that offer free stuff, especially in relation to education. Some of these sites could have really helped me understand something things much faster if I had access to them when I was still in school. Anyway here are some of my favorite sites...
1. FeedBooks <---- Contains a large database of public domain books and original ones.
2. Academic Earth <------ Contains free video courses from leading Universities.
3. TED <------Has some really awesome lectures
4. Stack Overflow <----- Just a personal favorite
