I tend to think of stuff in the wiki as things that appeal universally. (a wiki page on game programming on maemo, how the accelerometer works, etc). IMHO a garage page would be better for this since it is a fairly specific topic that won't necessarily appeal to all audiences.

OTOH, I'm but a sheep, and you the shepherd, Kathy :-) Stated a less Confucius-like way "You lead, I'll follow"
