Personally, I very much like the organic approach to PM'ing products you guys are pioneering, even if this particular project didn't go anywhere. I want to move away from a software culture where Important People hand down mandates to the developer masses. If the PM function can be accomplished organically, e.g., by one or two people who have opinions about where the project should go along with the ability to inspire others in that direction, and this works, it seems to me like such an arrangement would be far preferable.
