I think the reason people like listicles so much is that they give them something to argue about. I know this may be a shocking opinion, given the Internet's natural tendency toward friendship and harmony, but hear me out:
A couple day's ago I posted an article called "10 Great ABBA Songs that Are Not in Mamma Mia!" on Pop Offensive's Facebook page. It has since been shared dozens of times--most flatteringly by Carl Magnus Palm, the author of the book, ABBA: Bright Lights, Dark Shadows. And with that sharing came a torrent of comments. Most of these were either positive or offered considered disagreement, but there were also a few from people who were angry because they didn't understand how opinions work.
If you are reading this blog, there is a statistical likelihood that you have no opinion about ABBA at all. Still, you might get some delicious schadenfreud from my novice attempt at link bait.
