Games have a concept of "incremental discovery. Where higher level of complexity is revealed over time. I wish social profiles had a concept like this, where I have normie posts on my main feed, but I also have obscure posts that I don't want others to see unless they dig more into subtopics I post, a kind of "subprofile". I have lots of posts on linux I would like to post but I know most of my follows might not care for it. It would be nice if you could go to someones profile and subscribe to their “subfeeds”.
