Is that necessarily the case though? I'm hoping to see a lot more open source projects popping up on Kickstarter. While I'm not donating to Diaspora* (yet) I think I would be happy to donate to plenty of open source projects and Kickstarter seems to be a great platform for collecting those donations.
kickstarter isn't about donations, it's supposed to be about microfinancing startups. They are investments.
I'm with GP, these guys wouldn't get an inch with any angel or VC's so why are the general populace giving them their money? just because it's $20 it doesn't mean you shouldn't consider it in the same way as a $20000 investment. A punt is a punt, but you don't put money on a statement, that's what lobby groups are for.
Ah, they are explicitly not investments, so as not to fall afoul of securities laws. Kickstart donors get exactly zero property interest in any IP - check the FAQ. It's a sales outlet for custom products offered on a promissory basis.
