Dodginess abounds in Web 2.0. I have posted about it here and here. One of the worst locations for this on the BBC's Have Your Say page which is a playground for the permanently outraged and confused.
Someone has catalogued all this on spEak You're bRanes (a nod to Iannucci-Morris satire gem, The Day Today). They have even organised it into categories, like Armchair Generals, Curtain Twitchers, Unfocused Rage, Permanently Bewildered and Werthers Original Imperialists to name a few. Makes for great reading.
