When I was lamenting the (relative) lack of fluid dynamics questions in the chat yesterday, it was mentioned that I may not be the only one to feel that way given the number of people who answer those types of questions seems to greatly exceed the number who ask.
I was also looking at Map of all SE sites (except the 3 biggest) because I am really interested in data analysis and visualization.
Anyway, that got me to thinking -- has anybody ever looked at the distribution of users and the number of questions asked vs. answered? For instance, I've answered 22 and asked 0. On SO, it's 88 to 30. anna-v is 641-4, Qmechanic is 360-0. Obviously they are the big dogs and may not be representative of the community.
So has anybody looked at these kinds of trends? Are we "top-heavy" in the sense that we have many recurring experts ready to answer but (relatively) few recurring users ready to ask?
Is it possible for anybody to get that kind of data (questions asked/answered, number of answers accepted, etc), and if so how? (I answered my own question on this part with the Data Explorer)
I also wonder how physics would compare to other SE 2.0 sites.
I created a simple scatter plot to see what data we would be dealing with, the X axis is questions asked and Y is answers given. I'm looking for techniques on how to show all the different scales of data: http://stats.stackexchange.com/questions/45466/techniques-to-show-data-spanning-multiple-decades but it will give you an idea.
Also, should anybody want to play around with the data and see what they can come up with, the query is http://data.stackexchange.com/stackoverflow/query/88269/question-answer-and-comment-counts-for-each-user It pulls out comments too, maybe there's a cool way to incorporate that information. Cooler than just doing a 3D scatter anyway.
