Over the years I've experimented with several ways in which to organize the Youtube clips that I show to my students. For a while, I used Edmodo's video library, but found the hassle of signing in a bit too much for me and my fast-paced teaching style. However, I knew I needed something that was quick, easy, and cheap. Keepvid is just that.
