There's a wealth of instructional videos on the Web, but finding the one with the information you need can be a challenge. Enter SuTree, a social bookmarking site dedicated to lifelong learning. Whether your goal is to open a wine bottle with the panache of the waiter in the Four Seasons, juggle like a pro or make zillions in the stock market, you can search on SuTree and find a video somewhere on the Web. Some of the content comes from educational institutions, others from self-appointed experts, but everything on the site has been added by someone who liked it and then rated by others who have watched it.

Using SuTree is free, and all of the content it links to is also free. Registration is required in order to add content, but not for searching.
