I have just read an answer on Earth Science which left me with the feeling that we all have had on occasion: I wish I could upvote this more than once.
It would be nice if there was a mechanism to highlight such answers, beyond the generic site mechanisms like upvotes and accepts. A button like "Awesome answer" (also question?) which would propel the answer to a board of joyful reads if clicked often enough (and award the poster a badge). Such a collection of exceptional posts could potentially rival Munroe's What If.
Since such praise should be exceptional it would be fine if a user could only award it only once in a while.
Is there something like that? If not, would it be worth the effort to implement it?
