Nice idea. (Aside: I'm running some experiments on similar themes, the first one is at: http://inimino.org/pffs/experiment http://inimino.org/pffs/experiment )

Nice idea. (Aside: I'm running some experiments on similar themes, the first one is at: http://inimino.org/pffs/experiment http://inimino.org/pffs/experiment ) As others have said, the site would benefit greatly from proper use of Web standards and accessibility. Perhaps these problems are due to GWT. What you have is probably good enough to test the idea, so I won't beat this into the ground. As for the model, I think users are much more likely to fund software that they already know and use. Once software is actually released, it develops a community of users, some of whom may be willing to support it. Asking the small fraction of users with the foresight to anticipate using a program to bear the entire cost of developing it may work for a few cases (e.g. device drivers, or cloning existing software) but there are many other software projects that would have more success if they can rely on donations after they have been written and released. A model that finds a way for developers to work on credit against donations from future users would be interesting.
