I did, and read voraciously, at a pace and with a scope that now seems incredible to me.
However, even while reading, there's more than one thread of thought going on in your head, wondering about whether this historical figure in the book really did that thing, or whether you need to have that report in Tuesday morning or Thursday morning, or what this typeface is called and what its history is, and so on. Before the internet, I had to ignore most of these to get anything done, since I would have ended up spending a very large percentage of my time writing them down and researching them, and most of those thoughts just weren't worth it.
Now, though, I can put the book down for a moment and look up most of these instantly, and then go back to the book. Or not, because often the new questions that arise from the answers to these, and their answers, are more interesting than the fiction novel I was reading -- and this is part of my point: that the internet has both vastly increased the number of things I can find out about and my total consumption of information, and has greatly increased my average interest in what I'm doing, since I can stop and do something more interesting (in my own time) at any time. Usually whatever novel or textbook I was reading in the 80s was so boring that I wouldn't bother with it at all now, but at the time it was just the most interesting thing I had, and all the immediate alternatives to "read this book" were even more boring. I didn't have a great childhood, in retrospect, but at the time it seemed that my major problem was boredom.
I guess that's enough self-examination for one post. :)
