Please consider introducing a badge for highly acclaimed yet terse answers. The ones with links in them should not, obviously, count.
You can introduce a hard metric - e. g. >=10 upvotes for an answer that's <100 characters long. Or you can count the "milliupvotes per byte" (so that's a reasonably sized integer) metric for an answer and grant the badge above a certain threshold.
And then the SO administration can gauge the quality of SO content in hard quantitative terms :)
