I like this question.
Do you have friends and family to share books with? Discuss them with? Does it matter to you?
i do more now than i used to. B reads a lot and i can talk with him about books. If i read something really good then i might mention it to family. My friend D really liked the Twilight series so when i've found some YA books she might like i mention it to her. Mainly i talk about books online! With bloggers and on Librarything reviews and such. It both does and doesn't matter. if i read a book that i looooooove, then i'll be telling random work colleagues about it just to share it.
