Is it possible to do a list of SE sites sorted by the highest appearance of questions with a given tag? for example
StackOverflow 3970 questions ... TeX 119 questions
I was thinking about running a script looping on all sites:
for site in ['tex', 'math', 'meta', ...] open URL '<site>.stackexchange.com/questions/tagged/markdown' get the number "xxx questions tagged"
but I can imagine there's a more clever solution?
