I joined instagram a month or so ago, and I am an addict. It's all of the pictures I love from pinterest without all of the annoying instructions making me feel like I should be doing things.
I love the hashtags - my favorite is #readingoutside. I also love the pretty pictures of books next to tea cups. When I'm having a bad day at work (every day lately) I can look and be calmed instantly. Plus there are lots of clouds and sunsets.
I know I'm years behind on this, so if you're already on instagram please leave your name in the comments. I'd love to follow as many of my bookish friends as possible.
