Hi. I see by your reply that, even though you're not really new here (judging by your UID), you're not really sure how things work.
Slashdot earns money through advertising. More page views = more ads shown = more ad clicks = more money earned.
In order to drive the page views, Slashdot "editors" troll their readership in order to stimulate discussion through upsetting people, driving them to respond to stories they otherwise would pass up. They do this in several ways, including, but not limited to:
Intentional misspellings and poor grammar in the summaries.
Intentional inflammatory use of terminology (like this summary, which got you to reply (and I replied to the meta-troll))
Injection of political or religious themes or topics (a classic; never gets old, works every time)
And so on...
Now, with this information in hand, you can read the summaries and pick out the trolling technique used in about, oh, 90% of the stories/summaries posted.
