So this is separate from the Backer app? Because the announcement says that Backer projects can be funded through either Bitcoin or credit card.
You missed one important word, features. Backer only lets you fund THEIR projects.
I hate app.net and personally think it's a scam. Wtf would I pay for a Twitter clone. These people have delusions of grandeur and a great marketing guy.
No, you can fund features of any project. Btw, why so much hate? You don't have to use it or pay for it (there are free accounts as well).
@amincd: yes, this is the first backer project and it's about BTC payments of app.net subscriptions.
