There was a time when I would have answered this question with, "As often as I can". My high for books read in a year was 163 in 2010. Last year I read 39, which I realize is still a high number for some people.
I read quickly. I prefer print to ebook, but so many review copies are now only available in ebook form, so I've gotten used to reading on my tablet.
When I fell into reviewing, I tended to accept any and all books offered to me. Now, I've become more discerning in what books I do accept for review. It really has to grasp my attention. For the most part, I've stopped doing scheduled reviews or book tours, because I just don't like reading for a deadline.
I read every day. I don't always read review books. However. I always read before falling asleep. So my daily reading total is usually around 1 1/2 to 2 hours. Sometimes more, sometimes less.
What about you?
