ethereum-comments-protocolI’m one of the builders of Ethereum comments protocol; I wanted to come and say that we're happy to support/answer any questions around ECP. I agree with @byebyebye.eth that adding tools just for the sake of it can add unnecessary complexity for client devs - I've been there, it's not fun - so I think it only makes sense for Nouns if there's something ECP enables additionally.
I'm not sure of what the priorities are for Nouns currently, so it's hard for me to be able to recommend what ECP could enable additionally, however here are some examples in case helpful: an ECP channel hook could: Allow only Noun holders/delegates to post or comment, or optionally charge for posts/comments (could be in ETH or another token) to manage spam - but it seems you have a similar system already setup.
