Group dynamics are tricky right now -- too many cooks are in the kitchen, and no one wants to be stuck peeling the potatoes. In this crowd of egos, the best role for you is 'observer.' Watch for different ideas and help organize them. Keep people focused on the task at hand and help them avoid going off on tangents. In the end, you will have made the most valuable contribution by being the person that kept everyone else in check. Powerful people will take note of everything you did.
