Thanks for all the answers and suggestions.
What I find interesting is that the common reason for why a person was d/f was "other". I always assumed the list went porneia, apostasy, smoking/drinking/drugs/gambling, but it seems not.
It is also interesting that the majority left for doctrinal issues rather than either lack of love or scandal.
Blueeyes, I will make some new polls in time, and the specific doctrinal points will be a good one. Unfortunately with this poll software I cannot let people enter their own comments, so I will have to guess at the issues.
