I don't know about anybody else, but, I love history, geography, and almost everything related. I stumbled upon this excellent resource that is very handy and has taught me a lot. It is a website database thingy started by a university professor and is very organized. It displays everything from human evolution to American history to chinese history (world history). If it sounds interesting then check it out.

It would have been more useful back when I was taking history classes. D: Having resources like these are useful though, I have a folder of bookmarks dedicated to School-related stuff.
