After the ups and downs of 2001, do we want to even attempt to predict what'll be hot in 2002? Of course we do. We asked the questions, tracked the numbers, greased our elbows...and what we came up with are so many hot trends, we couldn't fit them all in this, our annual collection of predictions for the coming year. Listen to us, listen to the experts or listen to the entrepreneurs who've done it-but in the end, these trends will speak for themselves.
