Social media like Twitter aren't THAT useful. That's why they need addictive algorithms. Vine is probably the most useful because it is short but entertaining but sporadic. The real meat of nostr comes from things like @Zap Cooking that add a social element to a useful skill. There's creative avenues that can be noster based. Like exercise @RUNSTR or some weight lifting one. Hiking or foraging, woodworking or computer building. So many different niches that are all interoperable via Npub identities. We just need coders and niche enthusiasts to work with each other.
