I have just got the Taxonomist badge and whilst trying to work out what for, I took a look at the tags status page.
This page has numbers everywhere and is quite hard to understand. (example link)
The colors made me feel a bit weird starting at it for a while trying to figure out what the first column meant, but then I looked in the source code and I could see that it is called "Total Score".
I see that it is a tool tip that says it, however, it is not at all obvious. I have no suggestion on how to improve this, but I just thought it needs to be said!
