As a mod, I found this article of interest – because, frankly, even before I was a mod, I would regularly wonder “Why do people do this shit?”
Traditionally, trolls collected tolls. From an evolutionary perspective, this helped them acquire wealth, which in turn helped them to acquire resources / women.
I’m not reading the linked article bacause it may give me ideas, but I do not believe that “evolution” has much to do with mischief and trolling.
These persons are clearly avatars of one of the Trickster Gods (Coyote, Anansi, Loki, Jerry Springer), and are thus a matter for theologians.
What shit, exactly? 
Is it really trolling if you’re serious but alone in your perspective? As I understand it, plenty of people thought Jesus was a troll, and Gandhi, and Socrates, and Andrew Dice Clay. All were infuriating scoundrels in their time, now revered and honored.

That depends on whether you reason for posting it is that you honestly think that you are right and want to convince people or even just share your opinion, or if you just want to piss people off. The latter is trolling, even if you are giving your honest opinion throughout.
I’ve heard several people use it that way, some of them even former trolls. For example, Andrew Hussie, author of MSPaintAdventures.com, admits that he was trolling this guy who wasn’t a good artist, even though it was his honest opinion that the guy sucked. Ironically, the guy now sepcializes in an art style that is supposed to be inferior, and even has a comic designed to suck.
True, but it’s easier just to give him a link:
