So far, there's only a handful Lisp-related questions with a couple of answers, some better than others.
I hate web forums as much as the next guy. Long live comp.lang.lisp and all that. However, it's not really just a web forum; it features Reddit/Digg-like voting mechanism and wiki-style editing and it might be a good way of building a (better) Lisp FAQ of sorts, collaboratively. Seems worth a try.
