Reddit has that, and the ability to follow a user and get notifications when they post. I'm not sure it's widely used there, but I think it would be a decent feature to add to Lemmy.

I'd love that idea. Keep it private by default, but if people want people to follow them sure! If they want people talking on their page, sure. Etc etc

Honestly better that the mastadon/Twitter model to me anyways. Like there are few personalities I follow, and their communities are great. I don't really want disconnected no context verbalizing though like Mastadon/shitter does.

I personally dislike the user/profile centric approach of micro-blogging platforms like mastodon. Platforms like lemmy being based on communities instead is the single reason they are my social media of choice.

It's activitypub, but can be configured to also use AT as well.

Yeah, Wafrn uses both protocols, and basically runs its own PDS and AppView.
