I actually RE-discovered Discworld (have yet to get my hands on his other books) quite recently.
When I read some of the books years ago I didn't care that much as I was...well, pretty dull.
I left them for the sake of overrated anime and....
To be precise you can the recet Harry Potter movie 'blame' for me coming back.
It got me reinteressted in that fandom and from there....well...It's a bit complicated:
Normally I don't read other stuff while writing on my own stories (as my brain usually goes and clings to the 'fandom' instead of working on the original stuff). Though the HP books helped me back into a slight writing mood, even if it was ot full speed ahead yet. Then, maybe out of the fact that I don't like books 5 and up I picked up 'Interesting Times'
And oh boy was I in for a ride.
And yes: Discworld managed two things HP didn't:
1. I never had that many ideas for my own works
2. It took over my brain. Right now I AM writing a few fanfictions, just to get them out of my friggin' head.
