So you just wrote 'The Best Blog Post EVER.' You have a catchy tagline, some witty prose, and an awesome image (like the one above). You also have some social tools setup because (clearly) everyone is going to want to share your article as well. All goes well until... you decide to let facebook pick the image for you.
