First off, I apologize if this is a duplicate, I found lots of questions generally related to question/answer ratio, but none directly related to your score within a tag.
Basically, does the ratio between the number of questions you've answered within a tag to the score you've gained from those answers say something about your expertise within that tag?
Take the top users in the jQuery tag for example. The top all-time users in this tag have an answer:score ratio of over 2:1. This tells me they're pretty good at jQuery (probably an understatement).
However, take my profile for example. I have about 100 answers and an answer:score ratio that hovers around 1 for the jQuery tag. What might this indicate?
I suspect that the variety of questions, answers, and different dynamics within each tag muddle the usefulness of this ratio, however It's displayed pretty prominently in the top users area within each tag, which got me thinking.
