I used Flattr for awhile but I eventually stopped, because it had low discoverability of where the money was going and it was a recurring charge structure (as I recall), but sometimes I just wanted to spiff somebody one time. It's an interesting idea, but it never really worked out, and I also didn't heavily utilize it while I was active because few creators had a Flattr profile and the other mechanisms I was too lazy to use. A lot of folks here talk about selfishness being the killer, but the reality is that it didn't have a strong UX.
