Q:

What do the multipliers next to tags mean on the user stats page?

On the user stats page, under tags, what does the little multiplier indicate?  It's clearly not upvotes, as you can check anyone who's gotten a silver badge for a tag and see that the multiplier is much lower than 400.  So is it:

Number of questions answered that have that tag?
Number of questions asked + answered that have that tag?
Estimate of the airspeed velocity of an unladen swallow?
Something else entirely?

A:

How many questions with that tag for which you have posts (answers or question).
