I think this is an underrated aspect of Steem. I've heard all kinds of blockchains promise this is what will be done. Steem has already done this in practice and allows people to communicate together on the same platform. Maybe we need a few more years, especially with Steem.dao and soon to be SMTs and communities, but so far I haven't seen any critical issues with the model and it has faced a few challenges.
I also think a celebrity could have a hard time, however, they could also reach out to someone with experience. There are a few community managers and other talented people here more than capable of advising or helping out a celebrity. First, we need to get more readers. The content is alright.
