Yeah, I don't think the problem is too few Africanists. For me, it's that they're all working on political economy rather than statehood (save Reno), legitimacy, et cetera. It's odd, because it's a huge topic in the UK/France. There are some people in the US who do it - Dunn and Herbst - but they're at schools that don't offer doctorates. In Herbst's case, he's even left to be the president of Colgate.
Anyway, what I'm trying to say is that I agree with humanprovince. There are tons of Africanists, but finding overlapping specialties is difficult.
