I selected more then 4 Hours, as I usually spend at least avcouple of hours everyday catching up on news, new developments etc. and go through a rotating list of websites (think 150 at last count) which I check on a weekly or monthly basis.
So adding that to the hour or two I spend reading on weekdays and 3-4 hours o weekends, it comes to a little over four to five hours on average, with a larger share on weekends, holidays & sick days
If I started counting all the time I spend on mobileread, etc. I'll probably have to increase it by a couple of hours..
