I think you have a very fundamental misunderstanding about each of these networks and how they're used.

Your conclusions don't match with how people use these products and I say this as an avid user of Twitter, Facebook, Instagram and Reddit.

For example, to describe Reddit as the new Craigslist is completely off base. Reddit is the new Vbulletin forum software. Reddit is where vast and varying communities form around different topics and they all happen to have the same format but that's all that they share in common.
