It would be nice to see the topics I'm good at, i.e. the top tags that gained me some reputation.
At the bottom of the user profile page (which you can access by clicking anywhere your name appears as a link, like in top bar), you can find the (non-CW) votes earned per tag. As usual: hover the numbers to see a tooltip with details.
This should lead you to an overview of top users and you should be able to compare your position to others.
