Twitter is far more open than that. It's probably the only thing I liked about Google+ vs Twitter or Tumblr. You can choose to block certain people and limit your posts to certain circles or to just one person, thus it never shows up in the public feed. It's sad no one else replicated that aspect of Google+ or that it took off. It really designed better in terms of how content was dispersed from your account POV.
