What is the "411"?

I freely admit that I have little if any discernment when it comes to the TV shows I watch. My current shame is Gossip Girl.

• Finally a TV show about the idle rich and the trials they suffer
• Typical class-wars, middle class family in it for a good education, rich families just in it
  
• It is easy to forget that these people are supposed to be 14-17 years of age, they drink like fish and no one, not even their parents say a thing
• The leading lady (Blake Lively) is incredibly irritating, a moaning-Mavis of a magnitude once reserved for that one from Grey's Anatomy
• People have horrible falling-outs: making public who died because of who presence, etc and then talk about their feelings and how the "squabbling" was nothing more than transference of some other stress in their lives

But it is not all bad.

• The people are petty, shallow, materialistic & melodramatic
• There is Chuck Bass & Blair Waldorf- manipulative, abusive, self-centred- and- and manipulative

Were this an unweighed pro-con additive-subtractive decision... I would stop watching now, but really to borrow a fabulous in the tone of Kevin, the horrible people in it are- well you know- fabulous.
