We have some pretty nice stats in our Area51 page. Almost all green except for daily questions and answer ratio. While there are some things we can do about questions or visits (asking new ones, generating good quality answers and sharing both), the one we can actually work on right now is the answer ratio.
I've noticed lots of comments that would be great answers, but are not posted as such. I imagine the reason is probably that the poster doesn't have enough time to give them more content and prefers to leave it as a comment instead. But when I'm looking for help in stackoverflow, it's usually the short and straight-to-the-point answers that solve my problem.
Also, (in SO specially) I tend to skip the comments and go directly to the answers. Not sure if this is the usual behavior for others. So:
If you do, why do you chose to post answers as comments?
Would you be willing to post the same content as an answer in aims of improving our A/Q ratio?
