I'm not sure if I see as much of a shift away from using consultants as you do. I wonder if part of what you're seeing is that your own career is simply at a more advanced stage than mine (and many of us in the field). I see an overall shift in the workplace away from permanent employees and to more project-based work, and that means there's still a place for consultants. I am still getting work helping companies choose learning technologies, including traditional LMSs. I suspect that since your work is "on the edge" that your clients may also be on that leading edge of trends too. Most of us probably aren't that far out on the curve.

That said, I agree about the need to diversify your income and be ready to constantly reinvent yourself. Just because I'm not seeing the same trends as you right now doesn't mean I won't see it a few years down the road. I'm looking forward to seeing your insights and reading your book.
