All I'm asking for is a definition from as many readers as possible, because that's where a discussion is supposed to start. The (until this moment, at least) lack of a collection of definitions is actually horrifying, for me.

If we had a collection of definitions, you'd be surprised how different they all are (personally, I don't agree at all that "political post" can be defined by a list of words). Yet here we are, talking about something we haven't even clearly defined, yet.
