I've answered a few questions on SU over time, but am curious how many of them were correct (marked as answer). If we could have a ratio (for all time), that would be great.

The same can apply to questions too (which could be a gentle reminder that people are not marking as answer). So when I got to my question page, I can see a ratio or percentage ("You've answered/marked 60% of questions/answers")

So, in the profile pages we all have there is a section for answer and questions. Can we add some summary data, like ratio (or anything else)

It would also be great, regardless of the question or answer page of profile, to filter. So, I could see all questions or answers relating to Unix or W7 or something.

I admit the ratio is just nice to have, but the filtering would be useful, the amount of times I've tried to refer to a script I've answered to have to go to Google and search for site:www.superuser.com vba daverook ....
