Thank you for your points, they are very good. I agree that the lawyer market is hard to penetrate, and that students would be a much better target, so this is what we'll try to do.

As for your second point, due to a security vulnerability with having cached pages on the main domain, we moved them all to another one:

http://cache.historious.net/cached/354992/

I think that is much more readable, and the number doesn't really have to have a fixed number of digits; it can increment infinitely. If we ever need shorter URLs we can base36-encode it and reduce the number of digits right away.

Thanks again for the insight!
