Hey Robyn, thanks for the comment! What I'm suggesting is actually that coaching has already been as "mainstream" as it's ever going to get. (The bell curve has peaked and we're on the way down.) The opportunity of the next decade is to reinvent the way organizations are organized at a fundamental level, and with this re-creation, the talent profile of a typical "coach" will be utilized on the "inside" of a company. (Maybe my comment above will help explain, as well?)

The other forces we've got to contend with are the currently-shifting nature of what it means to be an employee at all. Currently we've got two basic ways to get paid from an org (W2 or 1099) and you're either "internal" or "external." It wouldn't surprise me at all if these lines get more blurry (or a third category gets added) at some point.
