As pointed out by some like nostr:npub1a2cww4kn9wqte4ry70vyfwqyqvpswksna27rtxd8vty6c74era8sdcw83a , speaking in smaller communities is very different from a wide, global audience. One problem that I hope to see solved in nostr is community discovery.
I want to have a full-blown convo with people about #fantasyfootball. A lot of people don't care about this topic and so I don't want to fill my feed or that of others with such content. Enter communities: I go in there and start a convo with people who are there for the same reason.
Going to be exploring communities some more this week. Hope to find some new friends or another side of people I already know.
