Wikipedia and rewards for knowledge sharing

Interesting comment from David Gurteen (one of the KM "gurus") regarding Wikipedia and rewards for knowledge sharing. I'm not sure that Wikipedia doesn't reward contributions - it may not do it in an obvious way (recognition etc) but I think it rewards one by making it easy ("We will do our best to remove technical hurdles because we like you"), being open (it's saying, "I trust you"), instantly showing you your contribution and not hiding it a black hole ("Thanks, and here it is") and connecting people via easy to make links ("You mentioned XXX and there's someone else in the world that thinks about that").

All fluffy and fuzzy rewards but, I believe, the ones that we all truly appreciate.
