I'm known as the Crazy Coffee Grounds Lady at work - I collect the stuff from the coffeemaker each day. Most of it goes into my compost bins, but I have thrown it onto the tomato patch occasionally, with no ill effect.

Although coffee grounds are brown in color, in the compost bin, they're considered a weak "green." This means that if you use them directly in the garden, they are a mild nitrogen-based fertilizer.
