This is really great. I always wished something like this existed when I was going through CS undergrad (and grad, for that matter). Have you tried reaching out to any CS professors to tell them about it? You might also spread the word by telling some "coding interview" blogs about it.

Feature plea: it would be awesome to have legible YouTube screencast videos of all the algorithms from sites like this for lecture purposes.

I teach various CS classes and love using these kinds of sites. It really is a powerful way to demonstrate concepts. Usually what I do is go to the site, choose an algorithm, then show the algorithm working with the default options. Then I'll change a few options and try it again. Then I might pick a different algorithm and do another demo. Then I'll share the link with the class and encourage students to experiment on their own to really understand the algorithm.

It would be convenient to have screencast demos doing the exact same thing as a backup for lectures in case there are any problems. Problems I've encountered: general Flash/JavaScript failure, projected screen resolution so bad that the site is unusable, site temporarily slow or down, sites with ads showing inappropriate content for classroom use. Video backup lets me not worry about any of that.

maybe ensure it can support the traffic first ;)
