The " Parse " purchase might actually be worthwhile ....
" This, in a way, gives Facebook its own mobile app framework but doesn’t necessarily put it into direct
competition with established app palyers. In other words, “Facebook apps” can work on any mobile device or in any browser without having to compete with the established platforms like iTunes or Google GOOG -0.53% Play or without having to support its own operating system. "
" By allowing apps on its own site to work with apps on mobile devices it ties users into itself on a level it hasn’t been able to before, and that’s a bigger deal for Facebook than it would appear to be at a first glance. It now has an entirely new way to help developers with discovery and monetization of their apps, which means a new money stream for Facebook. "
This means Facebook will create an app.toolkit. This will allow developers to develop apps on facebook home. I bet the next announcement would be a Facebook app.store. Also, like apple facebook may decide to charge to develop on the facebook platform therebye creating a revenue stream just like apple.
