The popularity of this site and its open source format, has created an atmosphere of conflict to the point where people are acting badly towards one another. While I greatly appreciate others sharing information that I was previously unaware of, often that information is incorrect or seriously flawed and without references. People are changing and inserting information that removes or confuses work by others that may actually be the correct information.
A system should be carefully devised to reduce conflict and ensure accurate information rises to the fore. This will help alleviate animosity amongst your users and provide a more accurate picture of history. A first step in this resolution might be a message window on each person page where contributors can more politely discuss these issues rather than just wiping out someone else's hard work.
