I met a software project manager once who argued that a team of good software developers would be a disaster:
"they would spend the whole time arguing with one another."
Ouch. If they spend whe whole time arguing with one another instead of delivering your project, they're not good software developers. They're crap, in fact. How interesting that this particular manager was unable even to imagine the qualities of a team of good developers, having never experienced one, perhaps!
There's a time to lead, and a time to follow, and an expert (in any profession) knows which time it is. If you find everyone else is talking to much, remember that it might be better to do the wrong thing than to do nothing. It will surely be a learning experience for somebody.
