Well, the faq does say no question is too small and I haven't found this question asked elsewhere so...
I'd like to suggest the introduction of icons for the badges, as seen in Team Fortress 2, Day of Defeat: Source or even Kongregate. Imagine your favourite badge transformed with a colourful and amusing image!
With a community as large and diverse as this one, we ought to be able to come up with some decent badge icons.
What say ye?
EDIT: How about them apples? (Just a sample of what's possible..)
