It's probably a bit of an odd request, but is it possible (or would it be possible) to have the ability to filter or group the User Reputation Leagues to those with similar skill sets based on the viewing user's Tags? I'm guessing I could rough up a OData client application to do this but I'd imagine other users would benefit from seeing where they stand in comparison to their SO (or other SE site) peers as well.
For clarification: I'm an active user of SO and I take pride in my current overall standing on SO. I commonly interact with the same users answering the same questions or answering the questions of the same users. It would be nice if there was a way to see at a given moment how my rep stacks up to those that I interact with regularly (even though it'd likely be discouraging). This could serve as a vehicle to drive further competition between users within the same bracket, as well as, serving as a learning tool for users that benefit from reading other user's answers.
Perhaps I'm the only one that sees value in having this, and if so then it's not a big deal (I can figure it out on my own) but it seems like something others could benefit from as well.
