I think some of the most useful sites on the net are:
Urban Legends
Truth or Fiction
Break the Chain
Snopes
... and their kind. Rumors do so much damage.
I am an inveterate coffee drinker ... have been since I was 11 years old (it was my grandma who got me hooked).
I grind my own beans (Eight O' Clock Columbian) every night and ready my coffeemaker so that I can shuffle out and press the button first thing in the morning!
I live more than an hour and a half from Starbucks. You have to pour your own in Gum Neck!
