AB in a nutshell is that if you have a question, you ask it. If you have an answer to a question - answer it. By most this is carried out in a normal balanced unequivocal manner, sometimes informative, sometimes witty, sometimes daft, sometimes unintentionally condescending or arrogant. Other times it is done intentionally with malice and venom.
If you can winnow your way through the Q�s, the A�s, the topics and the drivel � you�ll find a warm cosy fire with a nice cup of hot tea. A place of comfort and reassurance.
