i liked the concept of serving groups on nostr the way you originally articulated it. i think groups are great because they’re easy to get connected and see the right people/ideas to match your interest. much easier than with open publishing/feeds. maybe a good way to gather people before letting them loose into the wild open 😉
coracle has always been a feed system, too, right? have you considered moving away from feeds and just focusing the whole experience of Coracle on groups?
seems very differentiated and useful to me
