Good questions Dan. The discussions are primarily based around higher participation based on a non subscription model. That other sites have full free access, and use the pay model to eliminate ads and to provide more features. I've done this for a long time, and my model may be dated. That a larger majority of people are willing to put up with ads and the issues that even the Facebook group have had concerning personal attacks, etc. So I am reaching out to our users to get their feedback.
I will tell you that if money was my main concern, then I would run sites more like the motor forums - cumminsforum, tundraforum, ect. Those guys make a good living by selling sponsorships, advertisements, merchandise and such.
That's why I asked. The thing to remember is that as a sponsor, your experience wouldn't change. Moving to ads would only impact guests and non sponsors.
