Are there any statistics (perhaps queries to run against the database) about what features appear often in accepted answers?
For example; do most accepted answers have less than, or more than, X words? (I'm struggling for the language here. Sorry. I welcome corrections and suggestions for proper terminology.)
Graphs of the bell curves for "number of words" (on X axis) vs "number of upvotes" would be (I think) awesome.
I'm sure other people would have better ideas for what features commonly appear in accepted (or heavily upvoted) answers - amount of formatting; number of paragraphs; length of words, etc.
