Coffee: The god of small things:

 If you are a grad student trying to work late hours (because you were dallying during
work hours :-)),  Mr. coffee could perhaps be your best friend during tough sleepless times.

I try to taste a lot of different varities of coffee although, one life time seems too short for it. The coffee-fool  page whines about the deteriorating quality of coffee served in shops, and it is a matter of grave concern (yeah, right!).
