I've heard that sites like Guru may not be the best approach because so many people are willing to work for next to nothing. Seeing as I'm unwilling to work for $5/hr, this seems troubling.
I think I once saw a posting where the bids were between $2 and $8 per hour. And people wonder why no one wants to go into programming!
Plenty of people want to program. More so now than ever before. Just because there is a market for $8/hour programming doesn't really mean anything. There is a market for $800/hour programming too, and everything in between.
