Anyway, so I got together with a co-founder (a big open source contributor like me) and we built a cheap realtime pub/sub (push notification) service: https://baasil.io/#!/plans
We are like a tenth of the price of some of our competitors but our profit margins are still ridiculously large. I guess it's because we don't have to give our profits to hundreds of idle investors and board members. We just have to feed a couple of hard-working engineers (myself included).
I look forwards to this new age of frugality and restraint with open arms.
