Open sourcing the code base might help. I'm sure there would be no shortage of pull requests to improve all sorts of things on this site that could be improved without too much effort. Plenty of more than qualified readers here. Of course that would increase dang's workload, which I can imagine is not something he's after. But he could fix that by delegating to some trusted people.
But, with a site this big, any change is going to make someone unhappy. So, I can appreciate his hands off approach here.
