I've had an interesting experience with BNI. I had joined a group in April 04, which got shut down for lack of interest...we had 13 members, and had only 9 visitors in the whole year. So I transferred to a larger group, in Dec 04, spent the last year with them. We worked up to 30 members, now we're down to 23.
I finally at Christmas got 2 outside referrals, meaning people outside the group, not spouses of members. The chiro does not refer to me. I've done better with the realtor going to events with her...plus with her and her husb as clients.
BNI has been worthwhile for me. It has paid my dues+ a little more, I know, I know, it should be doing more than that...but it has contributed to personal growth as well. I'm a much better public speaker, have joined toastmasters as a result of BNI. I encourage everyone to check into it... http://www.bni-mn.com is our region's site.
