Obsessives. A Series?

We’re thinking of developing a series of articles around groups of Obsessives. At PSFK we really are fascinated with Obsessives, or groups of them, really fuel popular culture. In fact, what we assume as underground culture is actually culture created by Obsessives – culture that’s not on the mainstream radar yet. Their obsession attracts others to participate in their obsession and if and when enough people get involved (actively or as voyeurs), it spreads to the mainstream. Well, that’s the theory anyway.

So a question, for you readers… what Obsessives could we study and report on? Answers in the comments please.
