Slashdot posted a story about a coffee pot with "optical feedback" ... "that results in a highly reproducible means to brew coffee at the same strength time and again." But slashdot's readers provide more interesting reading. I never appreciated how much coffee means to them until reading the comments on this article. My favorite comment comes from a person who insists that to get a cup of proper espresso, you should roast your own beans and then spend $200+ for your grinder and $250+ for your espresso machine.
