It depends on the people in the group. In my experience there is a *great* deal of variance in the quality of groups from one to the other. Spend the time needed to find the right group for you. Be prepared to find a lot of competitive focus, strong egos, good-ol'-boys, and other non-sense, but if you look around you may find a group that is worthwhile for you. Also, don't let a small group of members set the tone for the entire group. I found that if you talk to many people you may find that there is a sub-set of the larger group that suits your interests even if the main group does not.
