- facebook enemies - for people who have invited me and I want to ignore with extreme predjudice
- facebook acquaintances - for people who I might meet once or twice but they are not really friends yet
- facebook co-workers - for people with whom I have a professional relationship with but am not really comfortable with them having full access to my profile
Facebook - Like it. It really has set a new standard in terms of a killer RIA.
People who want to be "friends" with everybody - Garbage
