However, Arrington claims there's a
gaping hole in the app universe: None have a direct payment platform to let app developers collect micropayments from users. So far, the only ways for app makers to collect revenue on their products
is to either charge one-time fees for downloads, or to sell advertising at low CPMs. Arrington believes that micropayments should become the third revenue stream, but he doesn't think that the likes
of Facebook and MySpace will launch a direct payments platform directly. "There's just too many headaches to deal with," he says. "Fraud, chargebacks and security issues bring real costs and real
liability. Duplicating PayPal's infrastructure just isn't cost effective."
A more likely scenario is for MySpace and Facebook to partner with a third party micropayments provider in the
same way they both outsource classifieds to Oodle. Apple, however, will probably do it itself, through its iTunes payment platform.
