Crypto wallets are not nearly as arcane as Solid. How many people have Binance accounts?
Market share matters, critical mass matters, adoption matters. I'm suggesting that mindshare goes negative over time if these things aren't achieved, and when you have long-tail blog posts trying to pump life into it, it's pivot time.
Righteousness alone doesn't win any of those things. It's been a very long time since Solid was released and it's like a whisper in the wind.
I do not have a Binance account and think cryptocurrency is a terrible starting point for a Solid application. Not even people who buy cryptocurrency care about where their cryptocurrency is held.
Arguably it hasn’t taken off because no one has incentivized using it.
