My dad read me Aldiss, Asimov, Blish, Norton and many others as a small child, so when I learned to read for myself I voraciously devoured all the scifi I could get my grubby little hands on... as a 10 year old I read everything EE Doc Smith wrote and begged borrowed (and even stole!) to complete my collection.
I'm a fast reader so I've always struggled to find enough to read, even now I still read up to a book a day (thank god for ebooks!).
I mostly swing between Fantasy/urban fantasy and military scifi these days but still sample freely across the whole spectrum of modern scifi, I rarely re-read or re-watch anything... there's always something newer and shinier in scifi!
But its Asimov and Clarke that really formed my tastes and I'm eternally grateful to them for the things they taught me, the sense of wonder, wanting to know everything...
