I have a few different topics I like to talk about, and I also like to have people with differing views on my friends list. Even though I disagree with most democratic stances, I like to have democrats on my friends list. It helps me see things from a different view point. As long as the posters treat each other with respect, I like these views on my lists. However, I also have times, I just want to speak to a subset of my friends. Not really as much, to keep others from viewing it, I have just have different things to say to different parts of my friends list.

Is there anything currently on CB that allows this? Would it be hard to add?
