The thing is, I think I'm doing OK. I haven't been on SO for that long, but I put in the time, I get the votes and answers and I am currently on #7 in the user league. But the thing is, no matter how hard I try, I won't beat Nick Craver. He has the girl, he has the score and I'm not going to get his face off of the user league.
But even though he does very well, he gets most his points answering jQuery questions and I'm a C# guy.
I envision user leagues based on tags. I know, tags can be changed and it may not be trivial to define how someone scored on a tag. But if you'd for instance include a user in a tag league when 50% of his answers are to questions with a specific tag, it could very well be representative.
And at last, I'll have a chance again.
OK, it's official, I'm blind. @Pekka answered that this already exists. However, is there a chance that this could look as nice as the normal user league, including the week, quarter and year score?
