Assume it was 1-click and 100% automated to deploy, run and update a Hub.

How much per month would you be willing to pay to run one? 

No direct economic incentive other than you know you're supporting Farcaster decentralization and you have your own copy of the network.

OK, if you're answer is you wouldn't run one.

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

I’d be open to run one, but it would definitely help to have some kind of direct/indirect incentive as running a node/hub, in my experience, almost always ends up getting more involved than what people are originally led to believe. For the culture? At most $10-20 and maybe a bunch of soft benefits like badges… etc
