Sandra, that reminds me of a friend who ran a facebook camping club with over a thousand 'members', and lots of interest in a campout. Only a handful actually showed up.

A rock club which demanded officers be on social media constantly--lost some good candidates, and has had 5 officers quit. Yet few clubs can manage to maintain a real website of their own.

Apparently FB is a good, free, easy way to get the word out about music events, etc. Though shutting out a good part of the population (many young adults shun facebook now, not just geezers) doesn't seem good in the long run.
