I see where Chris is getting at, but he's not generalizing it well.
I think a better rule of thumb would be:
Look at what new and upcoming technologies people with large domain expertise are excited about. Those technologies will probably be included in business practices within that domain in the near future.
Edit: It's also a rather self-fulfilling prophecy. Obviously industry leaders will pave the way for their pet interests to gain more mainstream acceptance, and at the same time those who look up to said leaders often outsource the mental overhead of investigating the newest technologies to leaders who's purpose is to guide the community. This cycle is rather exacerbated when a leader creates a new technology that he/she is now interested in distributing.
