Artists, businesses, public figures: How do you personally separate your social media?

I use Twitter, Instagram and Facebook. I follow a whole range of celebrities all over the place, really. Someone who puts up really good pictures, I will follow on Instagram. However if someone has a bunch of clever things to say all the time I will follow them on Twitter, although I don’t get the gist of Twitter much.
Facebook is more for friends, but I also follow some celebrities on there, as well as many pages on all sorts of things (musicians, brands, etc).

I use Facebook for following public figures, businesses, and political organizations. I like that FB allows the members to create their own system for organizing “friends” and “pages” into groups. In fact, I was contemplating separating the entertainers from the political pages in separate groups.

On instagram, I mostly follow people whose photography or subject matter I like, and am less inclined to follow public figures or people who are primarily seeking attention by posting self-portraits and such.
