Me, I just avoid calling anything a 'book' anymore.
All of us have, to some extent, accepted consumerism as a way of life: We want DVDs, and gadgets and iPods and fast cars and comics.
In the circles I'm in, it's books. And I ain't dissing that or calling it pretentious or anything, but if you're surrounded by a lot of bibliophiles already, the only way to differentiate yourself is to be specific.
It's like how there are PC fans and Mac fans, or gamers who are role-players and strategy grognards. All of them essentially the same hobby, but can be broken down further.
Me? The reason I avoid calling anything a 'book' is because being specific allows me to REMIND everyone that while I MAY be a bibliophile, getting me something like Rich Dad, Poor Dad is NOT a good idea.
They are 'novels' and 'histories' and 'biographies' and 'comics', to me and a book is merely the form --- dead trees bound together by a dead tree coating --- in which these consumer pleasures take shape.
