Open Collective!

Flattr is a social micropayment service, that makes it easy for you to "flatter" things on the internet that you like. When you're registered to Flattr, you pay a small monthly fee of your own choosing. At the end of the month, that fee is divided between all the things you flattered. You can even flatter things in the real world, with the Flattr Android app!
