Am I the only one who wishes they would charge for this? I'd love to start using it, but I don't know what their business model is or how they'll be using my data, so I'm far less inclined to start. If it were 5 or 10$ (or even more?) I'd honestly and happily give it a try.
It's not just about Prismatic going away. You can learn a lot about me by what I read. A popular way to make money is to sell that information. If I can't see how you make money, I'm going to assume you are selling my information. I'm not necessarily against that, but I really want to know what you are selling.
