Virtual Friends: In this first group are people I've never met IRL but am connected to somehow. This includes a good number of former ChicagoNow bloggers.
Virtual Randoms: These are people I've also never met but also have no tangible connection that I'm aware of other than we both lived in Chicago. There's probably one random leftover from MySpace.
Actual Acquaintances: These are usually people I met once or interacted with long ago. Former running group people come to mind.
Actual Friends: People I actually know and give a sh*t about.
Somebodies that I use to Know: People that use to be important to me but are no longer. But we kept the vestiges of our friendship through FB stalking and occasionally liking or the random comment.
