Goodreads is one of my favorite forms of social media purely for my own use. Although I always include a link to add me on my book review posts, I use it mostly to organize my own books. I used to keep a long running Notes page in my iPhone with book titles, which ended up being so long I would rarely look through it when I was planning my next read. But Goodreads changed how I organize my books and how I select what I want to read next. I love looking at ratings, seeing what my friends are reading, entering giveaways (although I never win - haha!), and voting on my favorite books of the year. I highly recommend creating a Goodreads account whether you consider yourself a serious bookworm or the occasional reader.
