It's hard to see kickstarter as the same type of bubble we saw in real estate or web 1.0. That type of bubble is driven by investor group think leading to absurd valuations.
Kickstarter is based on purchases (or donations), not investments. In other words, I don't think people are paying irrational amounts for your comic book because Kickstarter is so hot right now.
Now, if the pebble watch I just bought turns out to be a POS, I'm probably going to be a lot less likely to buy other new untested products on Kickstarter. So, a few high profile flameouts could damper the whole marketplace, but I don't think could lead to value crushing collapse like when a bubble bursts.
One of the more interesting asides here is PGs idea that our society is starting to reflect a power-law distribution. Not sure what he was thinking about specifically, but it certainly seems to be true in terms of wealth these days.
How does a society deal with that for the long-term?
We're going to work on making that really easy for anyone who's interested to see the ideas we come up with. Probably going to use google moderator to source ideas from occupations, and definitely using github for code that's created. We'll stick it up at occupyhack.com when it's ready (this is all being pulled together last minute)
