I think what happened was a migration of terms
A Troll was someone who attempts to annoy.
However over time a troll became someone who does something "annoying" thus a troll became an "annoying person" thus weakening the term.
This has never been the definition of an internet troll.
A troll is someone who intentionally trolls for emotive outbursts or some specific reaction or result, i.e. "fishes" (trolling is a type of fishing) by laying out bait and leading people to have the desired response. Not all trolls troll for anger - there are support trolls, and honestly they are some of the fucking scum of the earth, far worse than the anger trolls in all too many circumstances. Also, the common concern troll. The term trolling simply refers to the act of baiting responses (with the primary purpose being the response and the results, and the content taking a secondary priority if it exists as a priority at all).
And a large portion of internet users engage in trolling now and again, but are not, overall, trolls, since it isn't their defining pattern of behaviour.
I think the OP was mostly a waste of space, though - if you want to complain about people posting a tl;dr, knowing in advance that it is likely to be a normal response should indicate to you that you are
maybe doing something wrong. I
did read all of it and gained... well, nothing.
I honestly shouldn't have. It was kind of a colossal waste of time, since it was a point by point refutation to a site I ALSO gained nothing from reading.
I guess I should have known that in advance from the Rant label, though.
