hmmm, I've been using it since it came out and still use it. Yes the UI is a little crap but basically every time you post there's a tiny drop down you can set which groups can see and which groups can't. It will stay on whatever you last chose. Mine is set to "All Friends" except "DoNotShow" and there's about 3 people on my "DoNotShow" list. Have also excluded family for a few posts.
