I hope you'll forgive my not-quite-on-topic post here, as this seems the least-wrong forum in the list. My research group at MIT has released a tool to support voluntary donations to support web sites we visit---which I believe is a far better approach than ads. A user suggested that users of ad-blocking tools (like me) are some of the most likely to be interested in using it. So I'm posting here, looking for early adopters as well as people interested in helping us improve it.
Tipsy ( http://tipsy.csail.mit.edu/ ) is a (currently chrome only) open-source, non-profit browser extension that tracks (entirely private to you, in your own browser) the time you spend on different web sites, then divides up a total donation amount (decided by you) among those web sites in proportion to the time you spend. Web sites participate by specifying (in a small file on their site) a Paypal or Dwolla account that can receive these donations.
I'm strongly opposed to the Web's current ad-support model, but believe that we somehow need to support the sites that are providing content we like. I'm aware of other micro-donation projects like Flattr, Patreon, and Gratipay. But I don't think any of them are quite ideal for getting donations to content sites, which is why we're trying Tipsy (I'm happy to go into detail about the differences, but don't want to make this post long). Tipsy is entirely non-profit, with all payment going directly to the content sites, and collects no information about anyone. So I hope you'll give it a try. I'm also happy to answer any questions you've got.
Thanks for reading.
