Hey, this is a public service announcement.
A lot of authors have commented to me about having friends auto-added on Goodreads and they couldn't figure out why.
There are several reasons why but the main thing is when you sign up for Facebook, it will auto select an option to add the people you are friends with on Facebook. If you want to change that, here are the instructions.
Here is a link to the app page of your account: http://www.goodreads.com/user/edit?format=html&tab=apps
<----- the culprit. I unclicked this box.
And that's all you need to do. If you're still getting auto-adds, contact Goodreads customer service. They are awesomely friendly! :)
