I haven't been coming to this site for some years other than very rare occasions so don't feel my input is as crucial as others.
That being said, I agree with Shelter 100%. Don't let those big social media behemoths who only want to steal as much info from you as they can so they can profit from it cause you to discontinue a place of true discussion. Facebook is a lousy place to truly discuss anything or get to know anyone. I have wanted so badly to be engaged with fans of other bands as well and Facebook is the only outlet. And it's a lousy one. It doesn't work.
Places like this one and the offical BBS are important to the hard core fans. The fact that someone isn't asking on a weekly basis, "What is your favorite Tom Petty song?" like in groups on FB is reason enough to keep this "old fashioned" method of commuciation going.
