Great idea!! For many years, I tried to convince leadership in churches I've been a part of, of the necessity of doing what I call 'exit polls' of people who leave the church, to find out why they are leaving. Haven't been able to get any bites on that idea. I DO, however. like the idea about hiring non-believers to do a church survey. Seems like a reasonable thing to do if we're serious about connecting with the "missing."
