I think you have to be in the right mindset. Not to say its beyond anyone's level, but I think you have to be in the "mood" to learn about the material. I can assure you, there's been times where I would have hated reading it and times where I wouldn't have been able to put it down.

When I'm more focused on the here and now, I think I would find it a chore to get through. When I feel like I have less on my plate and looking for "interesting observations" it would work really well.
