I think there's a difference for me between reading and reading books. Every night I peruse about 100 different sites and their associated RSS feeds. So, yeah, reading has always been there for me, too.
Reading _books_ is another matter. It's always seemed to me that books require you to be within a subject or story for an extended period of time. Weeks if you're as slow as I am. And I've never been a very good reader of multiple books at the same time. Ultimately, things just progress very slowly for me when I do that and, eventually, it starts to feel like a chore.
Ultimately, though, I must admit that I am very rigid about such things. For instance, I will finish a book even though I don't like it since I feel like I need to get the full worth out of it. My wife, on the other hand, can not do that at all. As soon as she knows she doesn't like a book, into the round-file it goes. Another example is what I've talked about here: Worrying about liking several things. Isn't that just ... odd?
