Web 2.0 Reward System

Josh Bernhof, one of the authors of Groundswell, a book about using Web2.0 applications in business, just wrote an interesting blog piece Will online volunteers transform our economic recovery? on how reward systems are changing from money to more intangible, and I would argue more healthy, things, here's a quote from the article:

Amid the rubble of foreclosures and layoffs, this may just be a little green shoot that transforms the recovery. But in this new economy it will be reputation, support and sharing -- not just money -- that will make the whole thing go 'round.

I think it's always interesting to think of how these Web2.0 approaches will change the economy, Josh's ideas are very nice beginning.
