keybase had promise early on but kinda lost the plot. the vouching system was neat in theory but never really caught on outside a small circle. the crypto stuff definitely didn’t help, and once zoom bought them it was basically a ghost town, no roadmap, no real dev activity, just inertia.
feels like identity + trust systems keep coming back around but never quite stick. maybe too hard to balance usability, decentralization, and adoption all at once.
