I'm writing to let you know about a hybrid service that we've just launched. It's called ProcrasDonate and it helps people improve how they spend their time online by creating what we call a charitable incentive. That means repeated donations and relationship building for participating charities. So it's like a swear jar, but for internet addiction and online procrastination.
Our Firefox add-on which is now available for download in a limited beta.
I spoke at the Ethos Roundtable about ProcrasDonate here in Cambridge last week. The audio recording is here: http://ow.ly/YE6X

Thanks for your attention.
