That's quite hard to answer... When I was younger, I read almost exclusively fiction - pretty much anything ranging from classics to science fiction. For the last fifteen years or so, the proportion of non-fiction has increased, largely because I read a lot less for pleasure. If you counted blogs and other online writings as well, I'd say that most of what I read today is non-fiction. But I've always preferred a good novel to any factual book.
Good answer. Thanks. I tend to shy away from the '10 ways to X' blogs, and I could surf from Techmeme for hours if I'm bored at home. I like stumbling upon random people talking about their lives, sharing their experiences.
For example, I don't know the methodology for selection but each of the Blogs of Note all seem to be interesting in their own way.
