I'm receiving multiple similar emails from different people about the same set of causes. Sites like getup.com , dogooder.com and advocacysender.com These sites offer to back causes, monetising your desire to change the world for the better. That's quite a reasonable thing to do. But there's a lot more to the picture. While politicians traditionally took letters from constituents moderately seriously, and also petitions, the rise of internet based petitions has debased the currency. There's something in the investment you make in writing a letter, or signing a petition.
