I just thought of something that might be nice. How about you, in the very least, list bounties won somewhere on your profile? Perhaps this should even be public information. I'd like to see:

* Questions I've answered that have or have had bounties on them;
* Which of those I won;
* Links to those questions/answers;
* Bounties I've started;
* Total rep gained from bounties;
* Total rep spent on bounties.
