The arguments in the Fog Creek post sound right, and really resonate with those of us who are engineering/product people. But they don't match the reality of my own experience. At least for the high-cost, high-touch, long sales cycle stuff that I have the most experience with, the best salespeople all want their compensation to be heavily weighted towards commissions. So if you want to hire the best sales reps -- and, just as with engineers, you really, really want to hire the best -- you have to recognize and understand that preference.
But I'd be happy to be wrong about this! In addition to Fog Creek, I remember reading another blog post about a startup that doesn't pay commissions. Maybe a Foundry Group company: Moz? I can't find that post now, though.
