Add another divine apparently, between people who think that books can only be for reading or "using", and those of us who firmly believe we can have it both ways.
This has been addressed, but, I'd like to chuck in my 2 cents too.
For a book to be used and useful, requires the information to be immedietely accessible, easy to find, easy to read and consise. No excess verbiage, minimum of description and examples should be separated from the rules.
Now, that makes incredibly dry reading. Boring in fact.
So, exactly how do you get both? Unless you separate the elements out very strongly - similar to the White Wolf books where the flavour text and stories are usually at the beginning of the chapter and the crunch comes next.
The problem becomes when the flavor gets inexoribly tied to the crunch. People complained about ghouls and where ghoul paralysis comes from. Apparently we didn't actually know where it came from until 2e - a decade or more after the appearance of ghouls.
But, what happens when I decide that ghouls use poison to paralyze? I've had players in the past insist that flavor matters. That I cannot use monster X in this place because it's the wrong terrain (I had manticores in the mountains IIRC).
Placing lots and lots of flavour in the game raises expectations that that flavour will be used. Players make choices and assumptions based on the flavour. Heck, there's another thread floating around here complaining that creatures as PC's are not given "racial" abilities. That assumption only comes from flavour. There's nothing in the mechanics that state that all minotaurs use large weapons or all kobolds must have darkvision.
Yet people assume because that's the flavour, then it must be true in all cases.

On reading. I read some time back that YA fiction is seeing a massive boom in sales right now. However, only a small number of people are actually reading all those books.
IMO, that's pretty much the way its always been.
Jeff Wilder - you pshaw the idea that video games in the 80's wasn't a huge time sink. Trust me, it was. That bajillion hours I spent playing games like Bards Tale or Temple of Apshai or M.U.L.E or many others wasn't my imagination.
People don't read for pleasure. People have not read for pleasure in decades, if they ever did at all. Look at your parents. How many books do you think they read in a year? Look at your parent's friends. How many books? Reading for pleasure is not as common as people think.
