I imagine the breakdown is pretty heavily weighted toward free accounts. I wouldn't be terribly surprised if 90% or so are free - I know I have a few projects on there that are mostly idle deployments of weekend tinkering. Personally, I haven't made anything yet that is "big" enough (ie generating enough traffic/data) to warrant me taking the leap to a paid account. That being said, their infrastructure is such that I imagine free accounts only hurt them from a business perspective if they're consuming a lot of resources (bandwidth, processor time). And even then, if that is the case the user has probably already upgraded to a paid account. The overhead for idle projects is low, as apps are spun up on demand and killed for inactivity. As you said, it's a hell of a service. heroku create myawesomeapp git push heroku master Doesn't get much easier than that!
