A few years ago I prototyped a social network site with lightning integration. Worked well enough to load sats and use as sort of upvotes among users and on posts. Never released and stopped working on it because I don't think money should obscure merit of speech.
Much prefer the value for value model and I see a lot of value here. In any case it's good that zaps are optional and I hope ignored as far as evaluating whether to engage with a post. Glad to be here helping figure it out.
