It's interesting to peruse through the responses to Fast Company's Big Idea: "Within five years, technology will obliterate the need for business travel."
As I expected, there are 22 commenters who agree, and 92 who don't. Make that 93 as I cast my vote (or try to. The darn system keeps booting me out for some reason). But as the technology gets better and travel gets worse (both financially and experientially), I think it will make a dent in nonessential business travel. So as long as your meetings are really, really good, they'll still come. But they better be really, really good.
