I was looking at User main page and I saw that there is a set of three tags associated to each user name. I am wondering how these tags are chosen, how does the algorithm work?
I think These are the three tags that the user has generated the most rep from.
For instance, my own list of die2nite,xbox-360, & xbox-live-arcade are the tags that I have earned the most rep relating to. Here is an image that should give you a better understanding of what that means:
This is a breakdown of my rep-gain from the die2nite tag.
