Very very impressed. You do a search for droid, it asks you which meaning of droid, including the cell phone, the star wars characters, and three other meanings I didn't know existed. That questioning of which meaning of the word your looking for is an incredible innovation right there. It's also so simple a concept, too. Like so many simple ideas, I'm smacking my head that I hadn't thought of it myself. I wonder if they use wikipedia for the disambiguation.
