I wonder if there has been or could be a survey of the different academic fields amongst users on this site? I don't see that the necessary data exist at the moment, but I would be curious to see how broad a coverage of various academic disciplines we have.
I suspect that otherwise-small fields like Computer Science are over-represented (since StackExchange sites have historically referred to these fields).
I thus wonder if there's an inherent bias on this site towards the culture and norms present in certain academic disciplines (as well of course as the geographical bias towards US norms).
This is not to say that if such a bias exists, it is necessarily a problem. But nonetheless, the data would be interesting.
