Having received my Flattr invite, I’ve now added buttons to this blog and hope to retire early on the proceeds. (EDIT: They’re now just on the individual post pages, since they load rather slowly)
Flattr is a system whereby people can show their appreciation of content on the web. It works by allowing you to donate a proportion of a fixed amount of money every month to whomever you want. I’m setting aside 2 euros per month (but it could be any amount). If I click a Flattr button twice this month, two people will get a Euro each. If I click ten times, ten people will get 20 cents each, and so on. If I click nothing, my 2 euros will go to charity.
If you like my thing, and have a Flattr account, you can show your appreciation too. I don’t expect the get much, if anything, but the web is a free global publishing system with Google indexing it. If I were an upcoming musician, an author or an artist, Flattr might make my situation completely different.
