Tags to Post on Different Topics

Posters, which is a person, posts on the same topic all the time? What if, like me, who wants to post about wildly different topics, like gnu and steam rooms. You surely don't want to read posts about steam rooms, when you subscribe to hear about gnu. So, an entity (a person) cannot have different channels for each "topic"?

meaning, you don't want to subscribe to entities (persons); you'd rather subscribe to posts containing a set of tags from this entity. This is not possible in Steemit. Is there like a bug / feature tracker?
