Right on. Steem is a great way to get people here but to get them to stay is going to take engagement.
They're going to have to want to come here to have something with more value than the little bit of Steem they can get. It certainly adds an extra element of fun, but not enough by itself.
People will figure out pretty quickly that the Steem isn't worth it if it just feels like you're at a sales convention where the conversations are all just a one way pitch with the occasional empty platitude.
