I read about half and half when I am actually "reading" but most of my internet reading is nonfiction.

Might I recommend microfiction to the HN crowd. Sort-short stories (usually <2 pages) that are a great way to change your mental state into "fiction" mode without taking up lots of time (used on amazon for $0.01).
