Obviously fangroups and fen are quite dynamic and not the monolithic subculture they are presented as being.

Actually, I don't know where to get literature on this, but American Catholics and their responses to Rome - Vatican II, doctrines on birth control and homosexuality, advocacy of the war in Iraq. Kind of a very literal example, but the subcultures of Catholicism in America are very interesting and dynamic.

A few more:

Amish, specifically how they have adapted over time as technology has moved forward. Quakers could be intereting if the Amish are overdone in your course.

Cripts or Bloods and how they have responded to the influx of the Mexican Cartels and the Tongs/Triad incursion.

Any expatriot community or, perhaps more interestingly, American expatriot communities in different countries, such as comparing the American expatriot community in Tokyo to the American expartiot community in Doha, Qatar.

The Ku Klux Klan began as a anti-Republican secret society in the pre-Civil War North. As its ideas and membership circulated around, finding ideological homes in the South, it became what it is commonly preceived of today. Although I have not done the research to back it up, I am told that even today, the largest numbers of Klansmen live in Michigan, not Georgia.

There should be some interesting culture-shifty stuff in some of these. :-)

Also late to the party...you could discuss slash/fan-fic culture on the intertoobs....
