I'd like to see on my profile the percentage of answers that have been picked as correct answer, average votes on my answers etc.
I'm currently writing an app for that using the Stack Overflow API.
I hadn't wanted to say anything before it was done, but I figure I may as well let the cat out of the bag.
Think of it like BF2s.com for Stack Overflow.
I plan on having an alpha version done this weekend (Work keeps getting in the way). The domain has been purchased and the work continues.
