Nostr can have best of network user effect and themed spaxes (like 2002 forums). I imagine a load of interest/topic-centric clients to emerge soon. Like the forums we had before gravity of generalised social media pulled in users. Client for Trump fans (flags and maga hat branded), clients for different breeds of dog, etc, etc. The developers could even add extra useful features for their specific user group users, or run relays for their users. Community leader/"influencer" types will shill their users to their clients. nostr:nevent1qqstjsgupwzre96dk3r03c0nyy3agpm09nppg99zx70hrv3fsz8tsgcpzpmhxue69uhkummnw3ezumt0d5hsyg9e3ctwmngprhn264425hvffxsxcerflgzmursvcrejsffcl9qkpspsgqqqqqqsr2n38n
