Going along with my suggested implementation for Generalist, since the specialist badges have a gold level, I propose that the Generalist badge should too, called Polymath and, under an awarding mechanism like the one I describe in that other suggestion, requiring 5x the threshold of score that Generalist does. (So if Generalist were implemented with the 500 point threshold I just threw out there, Polymath would have a 2500 point threshold.)
The way Generalist wound up implemented, the wording for Polymath would be: "Provided non-wiki answers of 75 total score in 20 of top 40 tags".
