This area of astronomy still contains a lot of conjecture, as far as I can tell, and it could change. A recent Scientific American article made a case that black holes might not exist, but, instead, quantum mechanical effects would intervene and prevent a star from collapsing past the radius of the event horizon. They called the resulting not-quite-a-black-hole a black star (N.B., not the hip hop act featuring Mos Def and Talib Kweli). Black holes themselves are considered to have a spin, so since their radii are infinitesimal, they are the rotation champs.
