Ahh, OK I see what you meant. Looking down the list most seem to be reading fiction (mine is fiction with heavy theory and chemistry mixed in...ala Heinlein) or history. Frankly I don't have much interest in reading political books, but this is FR, so I would assume you would see more interest in that type thing here than in the general public.
I hated it when Heinlein would do that. I remember reading "Number of the Beast" and every time he would throw out some pointless mathematical formula my eyes would glaze over. I was a fan of his older stuff, The Moon Is a Harsh Mistress, Starship Troopers, Time Enough For Love....great stuff.
