Spoiler. The utility of the live call is overstated. Most of the people I interact via a phone vastly prefer async SMS over sync voice calls. We can do SMS via polling, the network doesn't need to push anything to us.

People text so much because there is an expectation the other person is going to respond pretty quickly. There is definitely value derived from having people accessible all the time, and I doubt a service would sell if people weren't.

  • Poll every X seconds if the last message was is no older than Y minutes. Poll every Z minutes otherwise.
