If you're not already on Goodreads, it is THE Facebook of the online reading community. Everything is focused on books, you can create reading lists, leave reviews, recommend books to friends and chat with your favorite authors.
And now, finally, I'm exploring it the way that I should have, back in 2012. But I'm a little slow, so bear with me. Thankfully, my Goodreads' hand is being held by SueBee, a Goodreads icon and Top Reviewer, who knows everything there is to know about this site and has been invaluable in helping me.
