It is sad but true that most groups would fold immediately if one critical person was removed. This is your baby and no one loves it as much as you do. You will probably be disappointed if you think that folks will come out of the woodwork to support and help you. Expect little feedback because most folks just want to consume a prepared meeting. Do not put out so much effort that you burn out.
Persistence is more important than a few labor-intensive flashy meetings.
Limit your time to about a day of work each month per meeting. Look for promising club leaders to share in club leadership, which can be richly rewarding. Running an Objectivist club is both challenging and extremely gratifying. The intellectual, social, and emotional benefits far outweigh the effort needed to keep it running, especially if you are web-literate.
