Thanks for the replies all -- maybe I should just concentrating on carving a small piece of what is already a huge pie. Your replies are definitely help me think in the right direction.

I just want to clarify one thing though -- I'm not asking "what is the next big thing" -- I don't expect anyone to know that (or to share if they do know). The main point to my question was, how do you follow trends, etc... to identify a new business area that has gotten hot, that would otherwise be completely off your radar? My goal would be to get in the industry while it is still young, and apply lessons I have learned from watching other markets develop. I'm guessing most of it would come from word of mouth or finding an article online about the subject.
