Very interesting idea, but there is unfortunately very little actual content. This list of all tags provides a nice overview of the range of the contents.
Yes, I hate to sound mean, but it would be nice to wait until there is more content before promoting.. I don't think it would be too much trouble to pick up a copy of "Algorithms in a Nutshell" and start populating the site on your own
