First of all, anyone that does that is nothing more than a coward. People use FaceBook, Twitter, MySpace (who is still on that, oh by the way) and any other social medium to do the avoidable -deal with issues. We are who we are because of the things that we do, so to know a person that thrives on the interaction of it, you have to know that they'll use that same methodology of interaction to avoid issues that THEY may be wrong in. Break by text; easy to do and avoids the 'why' of it all. Argue in FaceBook inbox; easy to do because then you're not dealing with the emotions that may confront what you did to cause the issue in the first place. The truth of matter is a lot of us are nothing but cowards and we use these "social mediums" to hide from the one thing that can change us into better people -the truth.
