The most important metric to me and many editors is how many quality articles we're producing. A major reason for Flagged Versions is that various content experts have told us that this is one thing they need if we want their help. So, one important metric I'd like to suggest is to survey and count the number of new editors who say that the new feature is a major reason they decided to start participating.
Also: note that Wikinews (en:wn at least) really wants sighted/stable versions displayed by default so that they will make it into aggregators, specifically Google News.
