We have a Yahoo group that is used to conduct team business through as a message delivery system. We also have a rather neglected Facebook group that is used to discuss news about the team. So long as it's not used to bash the school sponsors, FIRST and other teams I see no problem with it.
If it uis used a s a personal soundiing board for whatever vendettas are driving certain members then I would say get rid of it. Like anything else on the internet whether it's a group or posting on Chiefdelphi remember you are now in the court of public opinion. You have the right to remain silent. Anything you say can AND WILL be held against you (AND YOUR TEAM) in the court of public opinion.
So choose what you do wisely.
