TipTheWeb ( http://tiptheweb.org/ ) is a new (non-profit!) service that just came out of private beta a few months ago- it has no fees for tippers or publishers, and passes 100% of claimed tips to web publishers via monthly awards. And TipTheWeb doesn’t require a subscription or any kind of ongoing commitment. Both flattr and Readability take big cuts of the money before it gets to publishers. In addition to working with popular publishing platforms and independent websites, TipTheWeb allows multi-contributor sites, like multi-author blogs, to add simple metadata to their pages so that tips can go directly to the authors of the content being tipped.
