Mike - I guess only time will tell which young associates (in large signature firms) have actually been happy/satisfied with that role, even if they've occasionally complained about wanting but not getting their big chance/break; and which young associates have instead been painstakingly learning and working as part of a dedicated plan to one day design their own courses. Of that latter (and I assume much smaller) group, I think one or two might prove to be the right ones to try to leverage the signature name/brand as the first crucial step towards their ultimate goal. I think those of you who are currently working architects might be taking the "signature" in the signature firm more seriously than many of the rest of us do; as noted, for us APD is not all that much different than the Macdonalds and Burger Kings of the world -- a signifier of what to expect when you walk in the door, no more and no less. I think whoever will be working under that APD umbrella (no pun intended) just needs to ensure that the (well-established) expectations continue to be met, i.e. that if a client is expecting Macdonalds they don't give him MacRaynor instead. And if they do that, I suppose some young architect will have as much of a chance at making a name for himself/herself as any other young architect who is trying a different route.
