For those interested in such programming "puzzles" a good (and "language-agnostic") website is <a href="http://projecteuler.net/">http://projecteuler.net/</a> The puzzles are mostly based in mathematics and may not be "as fun" as the python challenge ones with their pictures and such, but I believe it is what some of the responders here said they would be looking for. In addition to that, Racket is rather underrepresented on project euler (13/180,000 users)<div>

Eli, your 'bot' attached as the backend to a wescheme style front-end editor could be the core of such an on-line puzzle site. We could even make it language-agnostic in some ways: racket/base, racket, typed/racket, lazy, algol60, frtime, etc. -- Matthias<br>
