There are many reasons to post. Some posts are worthwhile contributions; others may be made for the author to increase his or her "post count" or, for that matter, his or her own sense of self-worth.
I shall leave it to others to decide where this post falls. Of course, personally I see most of my own posts in the "contribution" category, but I am not blameless when it comes to George's examples of snarkiness. (OTOH, I'm not sure I've fallen into the "one-upsmanship" category; I hope not, at least.) But the car-wreck analogy is indeed a sound one, and often applies -- on a broad scale -- to definite "troll" situations.
Every online community involves people with a passion, be it about wine, espresso, art, motorcycles, politics, -- whatever. And passionate people often respond passionately. This is different than merely posting to "see themselves heard," so to speak. Some individuals are better than others at thinking before clicking "Reply," but opinions are fine --
as long as they are expressed as such. Opinions disguised as facts, however, are another matter. So, too, are unfounded accusations, personal attacks, and the like. I try to avoid making posts in these categories.
I know that I know
"this much" when it comes to the coffee/espresso, and that I have
"SO MUCH MORE" to learn. That doesn't stop me from posting on topics about which I know something, and -- to be honest -- I've commented on things in the past on which I have little direct experience . . .
but in those cases I have tried to make clear the depth (or lack thereof) of personal experience
and that I was expressing an opinion. I have always tried to make the distinction clear.
Not everyone does.
And there are those who always take some degree of delight in tweaking the tail of the "alpha-male" and then scampering up into the trees to avoid direct confrontation. These are the trolls.
C'est la vie. I am not sure one will ever be able to stop trolls. As for the gazelles, they know the lions can't eat more than one of them at a time, and it will take some time before the pride is sufficiently hungry again to launch another attack . . . they can graze in peace. People, OTOH, look at car wrecks and realize they, too, are safe . . . until they rear-end the car in front of them!
Cheers,
