This is a community without video and livestreaming in 2021. Especially amongst long term usernames.

Multiplayer game communities - not the watchers but the players - are also one.

I enjoyed the article but realized reading it there are different types of community. The form discussed there is more business/promotional, which is different from HN or MMOs.

Successful communities without any video exposure started ages before 2021, eg HN.

There are plenty that started in 2020. I cannot recommend any of them to you.
