I'm probably a weirdo, but the "write in books" is a massive no no for me. I can't imagine writing in a book (unless it's a total turd, but I assume we're talking about good, insightful books).
I do take notes, but always on separate sheets that I keep in the book. Just no way I'll write on the book itself.
