I understand that there is a SQL database type way of looking at activity on a stack exchange site - so if someone in the know could explain how to answer this that would be great.
Anecdotally I've noticed that there seems to be periods of time (during the day) when we get lots of questions asked, and then periods where lots of answering is done. Before making up lots of ideas why this might be the case (Students/Professionals?), it would be interesting to find out if it actually is true. Anybody got the SQL skills to figure out if questions, comments and answers have different intraday profiles?
