Shortly after Sustainability went into public beta, I asked on its Meta Do we want sustainability to be an evidence based stack exchange site? based on the references policy I'd seen work so well here.
We rapidly reached the consensus that while we might want to require all claims to be referenced eventually, for the moment we were happier without the more strict standard, in the hope that this might encourage participation in the site.
This got me wondering how Skeptics came to have this standard and when it was introduced. Was it here from the start? Was it introduced later, if so when? Is there anything Sustainability can learn from the experience of Skeptics having already created what I consider to be an evidence based stack exchange? Are we shooting ourselves in the foot hoping that we can introduce this rule later if we don't enforce it from the beginning?
Note, that Sustainability doesn't even have protem moderators yet, but I'm trying to think ahead for when we do.
