Having spent that past couple of years on a condo board, I agree with your summary above Having been involved with boards and committees in general for many years, I've found that the best way to get a know-it-all, loud-mouthed troublemaker to be quiet is to ask him/her to get involved. They either stop talking or they find out that it isn't as inexpensive/easy/quick to get things done as they thought.
I have always appreciated people who ask tough questions, but people who just like to get others riled up are a complete PITA
