All extremely good advice and very much something to form a habit in. But as with many things, I'm sure I slip here and there. Mostly I have been staying off of twitter because of this exactly, there are both experts tweeting out things - I think the urban warfare thing I have only heard of but was told it was from a military trainer focusing on that? - and psych-ops muddling the waters. I would like to say I can tell the difference, however that's often only hindsight.
