It's getting better.

The platform is being built.

As a few quick examples of resources:

Zapddit.com <-- Reddit alternative on Nostr. VERY early, only launched communities last week so people are still testing it out, but will eventually become a good way to find focused topics - Create your own to get started. If it has value, others will join.

https://www.nostrapps.com/ <-- This is mainly a link for apps, but to note is the fact that each app can offer an entirely different experience (music vs long-form blogging vs microblogging) with an entirely bundled userbase, because it's all Nostr.
