Interesting. I've seen hacker news before but I've never seen their code. In fact, I don't see it now anywhere either. Is it publicly available or was Hubski a somewhat official fork (IE: it was given to you guys)? I'm curious what language this is in. I did some searching and possibly a variant on LISP? I can't imagine writing something like this in LISP... performance must be a huge issue. I've only experienced LISP in AI research before, and the logic development in LISP seems nice for rapid logic development, but once you get into using it for practical purposes everyone I know of switches to C/C++ immediately. I've never seen it used for anything else, what are your experiences using it for development on web? I assume you're using a database of some sort, and I've just looked up some of the syntax for Common SQL. It just looks messy to me...
