Well I am one of the forum's spelling Nazis, and if you are going to quote a philosopher then at least you could get his name right. It's Hume not Hulme.
And what a pity you didn't go on to quote the rest of Heffernan's article:
Internet trolls regularly tread on gouty toes. They trick vulnerable people with whom they have no quarrel; they upset those people; they humiliate them; they break their hearts; they mess with them. They do it for something Hume didn’t perfectly name: the lulz — the spiteful high.
So do you troll? Trolls occasionally use hacking or identity-thieving skills, but you don’t have to have special skills to become a troll — just a cast of mind. Theirs is not a federal offence. It’s rarely even actionable. But, holy, is it mean. Stomp, stomp, stomp-on the parents of a young man who committed suicide. On a sweet girl looking for love on MySpace. On light-sensitive epileptics looking for information on a health site.
Then, when the ouch comes, or worse — gouty toes are supremely tender — trolls get their lulz.
Ring any bells?
As for the egrets, is that another lapse in concentration or your feeble attempt at a joke? (yawn).
