I read fiction really, really fast and people rarely belive that I'm doing anything more than "skimming" but I actually am able to understand and enjoy it, so I'm glad to hear you're the same.
I can read dry, boring papers quite quickly and get the gist, but I hate having to drag my way through them to get every last nuance or understand complex equations (my least favourite thing).

When I was younger (in fact, hell, even now) I just sometimes compulsively have to read. I used to scrutinise the back of cereal packets at breakfast as a child because my mother always forbid reading at the table. It gets sad when I read shampoo bottle labels in the bath just for the sake of reading.
