According to Urban Dictionary, you're "Pinterested" when you're "too distracted by Pinterest to be bothered to do anything else." I find I have this problem quite a bit. I also find that I get too distracted by books to be bothered to do anything besides read.
You can check out my Pinterest, where I've got bookish boards as well as lots of other assorted collections. Feel free to share links to your own bookish pins and boards in the comments!
