My answer to If Lanyrd allows anyone to edit conference information, how do you assure users that the information is correct? on Quora
The same way that wikipedia does—by relying on users to fix problems as they spot them. So far this has worked extremely well. We also prominently link to the official conference website so people can check the information themselves if they need to.
