I think post author missed the point of "lean". The point is to iterate through a few adjacent market positions with the lowest cost possible until you find one which resonates with users the most. Once you found one, by all means get out of lean and start building out like mad. This is an alternative to building out like mad something that you have no idea if anyone wants to pay money for, and then doing it again and again at great expense of time, money and morale. Think ".com" mania. I agree that Steve Blank needs to talk more about lean success/failure criteria and an exit strategy. If you've used lean to build a smallish business you need to leave it behind and go look for something else. This is challenging logically (how do you know if it's too small?), psychologically (given the sweat put into it) and financially (revenue is revenue after all and you get attached to it especially if you don't have other revenue to fall back on).
