The most comprehensive view of these issues of which I am aware is /The 
Sociology of Philosophies: A Global Theory of Intellectual Change 
<http://www.amazon.com/Sociology-Philosophies-Global-Theory-Intellectual/dp/0674816471/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1207143001&sr=8-1>/ 
(1998) by Randall Collins. Collins has a lengthy discussion of both 
Bloomsbury and the Vienna Circle as such communities, connected to 
philosophy (i.e. G. E. Moore, Russell, Wittgenstein, etc.). I have been 
working for several years on a loosely related project, provisionally 
titled /Charismatic Leaders, Intellectual Communities, and Allegations 
of Anti-Semitism./
