Flattr enables people to donate money to the content that’s freely available online. You set a monthly allowance on Flattr for how much you want to spend per month (say, $20), and it can split it up among the various creators you donate to. Last month the service switched from requiring content creators or services to embed a Flattr button on their sites to a model in which you reward those same creators just by using many of the social networks you’re already plugged into. Perhaps the best example was of the new model was the process of making a Flattr payment when clicking the “favorite” star/button on Twitter.
But as of today, you can no longer do this.
