At Indus' suggestion, I have decided to carve out a little section of the FAQ and devote it to beer. Everyone please feel free to add your thoughts on this wondrous gift to mankind. I'll kick it off with a limerick I wrote when I was in Dublin...
There once was a lad from Dublin,
Who asked why his Guinness was bubblin'
Said a man by the door,
"Have a few pints or more--
With such questions you'll no more be troublin'."
