I was thinking about this earlier and I had a thought. Bare with me. Back when I did Facebook and I would search for an interest, a number of groups would show up with said interest. I was not drawn to the pages that had 100 members, I would join the ones that had 1000's. High energy pages with lots of posts. A member count IMO only helps the cause, I do not believe it hurts. I could be wrong.....
