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.

alertcaster.xyz // monitor Farcaster for interesting new content

i already index all of Farcaster in elasticsearch for @alertcaster using the APIs. running a hub adds cost and complexity that's unnecessary today

best farcaster developers build on neynar.com | /neynar

andyjagoe.com // denim.vc // tokenizing real-world assets / onchain venture funds @fairmint // @alertcaster 

Yep, but we're going to be deprecating Warpcast APIs at some point (folks like @neynar will likely have a 1:1 replacement)
