I think it would be a great idea, it would educate people more on what the JWs have done and what they believe in before they came knocking on the door. I think more people than just JWs and x-JWs would be interested, for example anyone that is interested in the bib or religion, and it would give them valuable information to tell any JW they know.
One question though, who would fund this and where would it be located?
