You make good points. I mostly agree. I do return to down modded posts, and look at them objectively. I've learned. I've changed how I write, and what I comment about. But I've also learned to avoid comment minefields.
There are certain subjects where reasonable posts will be bombed. But not nearly as much when those same posts are made anonymously.
I agree about ranters. Mr. hosts is obviously a good example of this. It was/is kind of humorous to see his several dozen posts in a row, on this thread. This guy must have many computers lined up to post from, given the daily limits on AC posts. He has issues, indeed. But no more than goats link posters.
But in, for example, an Apple thread, one had best be very careful what one says. To the point where I no longer even read Apple threads. This is mass mod trolling in action. Mac fanatics with mod points.
I should point out that, as much as I'm saying mod stalkers are a problem on Slashdot, forum/comment deficiencies are much more of a problem anywhere else you go. Slashdot comments, mods & meta-mods are the worst system ever invented...except for all the others.
Here's to Slashdot. May it remain free from the promised Beta/Downgrade, and may it stop linking to Medium.com
