Answers.Text: The purpose of creating nucleation sites is that it creates and maintains the head.  That is for aesthetic purposes, but the head also brings beer aroma to your nose so it adds to the perceived flavor as well.

  The widget is for aesthetic purposes only. Some people think it looks better with a head. But it flattens lager.
  
  I refuse these glasses in pubs as I like a lively lager.
  
  Test it yourself. Test two lagers in two glasses. One with a widget and one without. Taste the difference at the end of the pint. The widget flattens the lager by removing CO2.
