Glyn Moody writes "Diaspora, the free software project to create a distributed version of Facebook, has been much in the news recently — not least because it has raised $170,000 in just a few weeks. But what's also interesting is the way they've raised that money: through a series of graded rewards for pledges of financial support. This is an approach adopted by some forward-thinking musicians: for example, Jill Sobule funded her last album in the same way, garnering $75,000 in pledges from fans. Is this a model that could be applied to other free software projects, or is it just a one-off?"
