It's not that we don't have people that would qualify (we do), but that particular badge has an added stipulation that the top 40 tags on the site must have at least 200 questions each before any of those shiny silver badges are handed out.
This has always seemed to be far off in the future, but looks like we are finally going to get there!
At the current count, we already have 34 tags with the required 200 questions, and the six tags closest to the limit (puzzle-creation, number-theory, game, rubiks-cube, anagram and password) are a mere 134 questions short, in total.
The answer below will keep updating periodically, and if you'd like to place bets on when we'll reach the mark, do drop a comment below! Juicy awards (If I can think of some) will go to the best guess (taking the time of the guess into account), and artificially manipulating the result is totally allowed, as long as it's done with great puzzles being added to the relevant tags!
