Wasting time on YouTube? Watch out, you might learn something
The world’s biggest video site, YouTube, is like a public library. It contains pretty much every kind of video, just as a library contains pretty much every kind of book. YouTube gets a lot of stick about funny cat videos and other amusing fluff, but this is no reason to avoid it as a low-brow site. Who would avoid visiting their public library for serious research just because it also contains tacky romance novels and ghost-written celebrity autobiographies?
