Thanks for the feedback! We're going to work on that. We've got some architectural advantages vs. Heroku that we think will become more apparent once we get some new features in place, but right now the main benefits vs. Heroku are WebSockets, the ability to persist data to local storage (for running databases/etc), and much simpler/cheaper billing for the beta. We're trying to come up with a way to summarize this in a bumper sticker slogan :)
