Haven't read thru every response, but it's funny this topic is on here... because when I got into DTW on the inbound and outbound of my trip to DUS over the past couple of weeks I have made comments about exactly this to whomever I was talking to.

Seems like I get stuck waiting right outside the gate for the ground crew to direct us in the final 50 feet more often at DTW than any other airport. Aside from that, it's a wonderful terminal... but the waiting is starting to bug me.
