What will editors do after they leave? There is an enormous amount of available time and attention span that could be spent on other valuable projects for mankind.
Thought about that too. I think http://www.openstreetmap.org/ is similar enough in at least one respect: You describe the part of the world that you understand and know best. But maybe contributors concentrate their effords on their own pet project or spend their time on twitter.
I wonder if history will repeat itself and lesser geographic locations (like narrow alleys or something) will get deleted from openstreetmap because they're not deemed important enough by the ruling elite.
Hopefully they'll help clean up Wiktionary. I downloaded the English dataset the other day and it's a mess. IIRC, less than 1/3 of the words are properly tagged as English words, and a significant fraction of the words aren't even rendered in the English character set.
The good news is that the editorial standards are extremely consistent, so it's easy to extract information. They also allow batch updates, so if I find an easy way to correct vast swaths of this data, I could send a batch update file once
