For the average normie letting google remember it is enough.

Better key management options are required, but I don't see anyone making new accounts saying they lost their keys.

People mostly just vanish I assume because they didn't get the traction they expected or they couldn't find people worth following and got bored.

Lack of algorithms is the best and worst part about nostr, it's a learning curve after being programmed to rely on them.

Really need one that shows all the new accounts to each other so need people can find each other.

People will share an introduction note, but never check the hashtag themselves.
