Flattr, the micropayment startup founded by ex-Pirate Bay associates, has opened to the public today. No longer will you need an invite in order to add the Flattr button to your web site as a publisher or to give support to the sites you visit with real money.
This is a really smart program. This could actually work, assuming they can convince the general public (like me) that it's worth putting aside 5 to 10 bucks a month to give to people/content they like. If they could put in some sort of Karma/reward system to create some sort of benefit for those who give, it would be all the better.
