Would love to comment with feedback but I'm not techincal enough to use it! Sounds like a time-saver though. Do you have any plan with Dotfilehub? Sell it as a product, keep it free, accept donations if it becomes widely used...?
I don't think I'd ever want to accept donations or sell it. It should always be pretty cheap to host unless it blows up, which I kind of doubt. But who knows!
