The word that I haven't seen yet in this thread that comes to mind is "toxic". Yes, updates to a lot of Apple's products are delayed. Yes, I am really eager to see them arrive too. But a faction of commenters here on MacRumors have taken that as their license to complain endlessly on every single story about how Apple is horrible now and Tim should be dead and Steve should be reanimated.
The difference between these folks, and someone on a drunken rampage is, the next morning the formerly drunk person will generally apologize profusely for their behavior and feel ashamed of it. But these folks spewing toxic sludge into every thread here... if they finally get, say, a shiny new MacBook Pro that they love, in two months, or six months, or whatever, I have no expectation that they'll come back here and apologize profusely for being such dicks and yelling over every thread for months on end.
MacRumors could post a (somehow Apple-related) story about "Puppies are adorable", and it'd get 100+ comments from people angry they still don't have a new computer/phone/widget today (which is entirely different from the seven stories yesterday on which they bitingly commented that they still didn't have a new computer/phone/widget yesterday). It's getting to where it's hard to discuss the actual content of a story - the intended purpose for these forums - because of all the bitching/moaning/whining negativity one has to wade through to find the comments that are actually about the story, rather than yet more toxic whining. And it's kind of killing the MacRumors forums.
