It took me a while to start reading Pratchett because I was fed up with all the fuss over him. Then I ended up being involved for a while with the first Discworld fanzine in the UK...
On the other hand, I only read Lord of the Rings because of all the hype, and, well - I'm glad I did because it has allowed me to make my own mind up about it, but aside from the historical significance of the books, I still don't see what all the fuss is about.
On yet another hand (Marc - what was in that last ZCP I had? I seem to be mutating into a multi handed being. I'm kinda hoping it stops at 8...), I didn't dare read anything by Thomas Pynchon after I'd read Mason & Dixon as I was scared the rest of his work wouldn't live up to the hype or my expectations.
What was the question again?
