I like trolling. I just wish you were better at it.
The art of trolling has for the most part been lost, in the same way and for the same reasons that the rhetorical arts of Attic Greek have been lost. So few people appreciate Attic Greek today--even in Greece--that even a skilled rhetoricist would go entirely unappreciated, no matter how good his arguments or persuasive his propaganda.
Long ago, before the Internet, before anybody knew what HTTP was and Usenet was king, people understood what trolling was and how to react to it and appreciate it. There were competent--nay, brilliant!--trolls and contemptible trolls, and everything in between.
Now, almost nobody remembers old-timey trolling, and so would-be trolls of the old tradition have no real way to develop their skills and no bar against which to measure themselves. Both ingenious trolls and sloppy, lame, half-witted trolls get bites from all directions, so there's no way to know for sure how good one is or how to make oneself better.
It's true that sherp has potential that he isn't exploiting, but in his defense, his environment is working against him.
