@tripleee that is the accurate question count per tag. Tags does have a count field that should match the outcome of your query but I never checked if it does match, nor if such difference are semi-permanent.
@tripleee I didn't notice but also didn't pay strict attention to it.
for the Pets meta trivia: maybe it is fun to do the postive scoring question and answer with the most characters (best done against posthistory text field) and the minimum characters. And then extend to rep per character for the OP.
In that same manner: which user leverage their use of characters the best (aka most rep from low number of characters in their posts) and which should get an A for effort (aka: most characters but not getting as much rep for it)
