Unless I just can't find it. I can't seem to remove certain people from my feed anymore without unfriending them. That has made Facebook pretty awful for me. Facebook serves two purposes for me: to share photos of my daughter with my aunts, and to rarely contact someone who I don't see often. I thought that Google+'s circles might work better, but now I think the ideal 'real name' social app would basically be an address book in terms of connecting to people, but my feed would be disconnected from that. In fact, a feed would just be threaded conversations that someone intentionally started, and you could participate if you were invited into it. Only people in these conversations could see them. The last part would be that every account could have a mini-blog/photostream, and the owner would decide who could see it on an individual person basis. No default visibility at all. You can partially acheive this with FB and G+, but here, I think what you can't do is perhaps more important than what you can.
