Find out which question/answer awarded you the badge
Jeff stated that a background process runs to figure out how many badges you should have. I can understand this design. It solves a lot of problems. I can also understand why it's then hard to figure out what question awarded you a badge.
But when you look at the Great Answer list it shows the users who received a badge. We should be able to show the answer that generated the badge I would think. Now Great Answer isn't too terrible because you can figure it out from a user's profile. But what about Necromancer? Or Tumbleweed? Or even Populist? It would be really nice to see this information.
