I agree completely.
It seems totally backwards for a site that is supposed to encourage sharing and connecting to others by broadcasting a wide range of interests online to not have a way to actually stay connected to those things.
It's just stupid. Sorry, but it is. The ability to subscribe to my favorite artists is the sole reason I joined livestream years ago. If I wanted to just pop on randomly and hope I can find something cool, I would just do a google search.
Sorry, but it's very frustrated and completely counterintuitive.
