Revenue distribution is an interesting variation of Flattr.com's business model. Flattr is more general as it's a platform for distributing micro-donations to creators of music, games, etc., whereas Readability is specifically about publishing and effectively offers a product/service directly to micro-donators. You could see the same model being applied to other verticals.
