Why would that not be prone to the same issue you think Wikipedia faces?

Maybe it would not, but putting all your eggs in one basket has never been a good idea either.

Superior methodology (transcending numerous cultural / psychological / cognitive norms and obligations) is how I would go about it.

For example: banning the conflation of opinion and fact, like what's going on (and always goes on) in this thread, a behavior that is protected (doing otherwise "is not what this site is for").

If an imperfection is noted: log it, investigate, improve. Rinse, repeat.

Also: best prepare one's will, life insurance, etc before undertaking such a project.
