I work at New Relic, so I see a lot of companies (startups and otherwise) that have apps deployed on Facebook. The traffic they get is _insane_ and I don't see any indication that it's slowing down.

Games are an obvious category where Facebook dominates, but they are quickly becoming an obvious destination for new apps to launch, given the access to their social graph and the viral nature of the apps in general.

This isn't about hosting. This is about creating a living Facebook app in 5 seconds.
