I think one issue with Wikipedia is it started when people still thought anonymity was great. (E.g. look at Craigslist compared to more modern sites like Airbnb.) So it's harder for editors to be accountable or for their biases to be known. I think Quora's approach is better overall, where they allow people to select anonymous as an option.
