The experience I've had with dealing with big corps is very much "hurry up and wait". Often this is a symptom of the structure and politics of bigger institutions, where you don't have to convince just the person you are dealing with but convince them to convince others. If they decide to try to bring you in it is their reputation on the line, a reputation that could be damaged even if the deal never goes anywhere.
I've been caught in the middle of some nasty office politics that have totally killed negotiations because I had the wrong guy championing my cause.
Oh and does it strike anyone else as a bit unprofessional to go posting correspondence to the world? I'd certainly think twice before dealing with anyone who had done this in the past, talk about burning bridges! Or am I alone in expecting a certain measure of privacy in my business comms?
