We were specifically talking about Patreon, could you please clarify why that would need a smart contract? I don't see it. I see how you would perhaps in some complicated convoluted way to implement the whole platform on a smart contract, but at that point (if we are going that route, without having a central website at all) - what is the point of using contracts at all? It is way more complicated than just publishing a bitcoin address on creator's website and be done with it. People already think that is complicated, imagine what they would be saying about "smart contracts".

Patreon does not have a limitation of a funding goal usually, it just sends all the funds directly to the creator. It's not like kickstarter.
