I have noticed that during the summer there are fewer questions (for the simple reason that there are fewer students taking courses, and hence fewer things to provoke questions).
I was wondering (purely out of curiosity) if there is a graph somewhere of questions vs. time? It would be interesting to see how this varies throughout the year, and to know quantitatively how many more questions are asked during the term, etc.
(In the same way that searching math on google trends gives an interesting cyclic pattern with highs near exams, and lows at Christmas and summer.)
Thanks,
