Out of curiousity, have there been any other forks that have focused on editing the content? I mean, I know there's a bajillion wikipedia mirrors that are just trying to get page views for cheap, but have there been any other forks that are actually trying to bootstrap from Wikipedia and make changes to the underlying content?

As I sometimes mention, informally studying the effects of code structure on community creation is a bit of a long-running hobby of mine, and I'd be intrigued to see any other extant examples of a wikipedia fork.

It's also extremely unlikely to ever get enough traction to steal even a tiny fraction of wikipedia's user base.
