In reply to markk5.

The point is that in the end an expert need to have some kind of profit (money or other) to share his advice.and without it sooner then later he will stop and the only people that will remain in the group are the people that ask questions and not those that can provide answers.

Definitely a legitimate concern but I've witnessed time and time again, developers willing to stop and lend a hand when need be. It's not sustainable if it's the same people over and over again but that's the beauty of having over 7,400 members, despite most being lurkers. There is generally someone within the skillset likely to jump in and help out if they see a problem they can help with. StackExchange is setup in a way for user's to spend time there, answer questions and gain credibility. The group on Facebook just answers questions to the best of their ability, no rep, no street cred needed. Just the satisfaction of helping someone get to that "ah ha moment".

It seems as though you have profit on the brain and I can understand that but it's not always about fame or fortune. Sometimes it's just about being in a community of people with like minded interests and talking about things, sharing ideas, and helping others in a friendly atmosphere. That's what the Facebook group enables.

Maybe I'm taking this the wrong way but are you against participating in the group solely because there's no profit (rep or money) in it for you? It's just a waste of time?
