I had a short discussion the other day about micro payment solutions to support creators, specifically bloggers. I’d like to know how many platforms there are for this sort of thing. The ones I know about are Ko-Fi, Flattr, and Liberapay. Are there more? Which ones are popular?

I’m planning to do a little bit of research and write a blog post about it, but just finding answers to these two questions appears to be a bit of a hurdle.
