I‘ve occasionally complained about the lack of attention to secularity and nonbelief as an academic area of study.
Fortunately, this appears to be changing. There are enough nonreligious people around to justify some social scientific interest. Enterprises such as The Non-religion and Secularity Research Network are up and running, and should produce some interesting stuff as the field matures. (I fully expect that there will be plenty of information coming out that will not flatter secular people as well as material that confirms our self-perceptions.)
Meanwhile, the work of NSRN and similar organizations are worth paying attention to.
