Lol - I feel a little bit odd here since I've never checked my reading speed.
I guess it's a little faster than how my friends read due to the fact that my english improved a loooot since I've begun reading fan fics.
Anyway, it's probably pretty slow compared to yours
But honestly I don't mind - often I get frustrated when a really good and intriguing story is over so soon
I hardly find time to read for several hours - my normal time is about half an hour before forcing myself to sleep and about 15 minutes during my lunch break at work or at university.
I'd really love to curl up in my bed and engross my mind into a great and long (which means 500KB+) story, reading sloooooowly and re-reading every sentence several times
Best,
Jana
