An interesting idea: App.net will be paying “at least $20,000 per month” cumulatively to app developers, divided according to each app’s popularity and user satisfaction ratings. So a reasonably popular app might get a few thousand bucks a month.
It’s a strange move, though. It doesn’t look confident. This reminds me a bit of RIM’s strange $10,000-guarantee-if-you-make-at-least-$1,000 deal. (Apple and Google never needed to pay developers to make apps for iOS or Android.)
But it might solve the awkward question of how developers should price App.net clients, given its small userbase.
