I participated in a very small conversations about authors' privacy. Someone was concerned about how much biographical information there was about authors now. In all honesty she was appalled at what she could find out about the authors, just on their back cover flaps or what was read after an audiobook.
My comment was that many of the younger writers grew up in a world with email, MySpace, Facebook, and other such social media. They're used to putting everything out there to share with their friends. I think that writers of that generation are going to feel a lot more comfortable with detailed bios than those who grew up without such social media.
What do you think? Do you find that bios have more information than you're comfortable sharing about yourself? Or do you think it's a great way to connect to readers?
