Facebook allows us to communicate in ways that were unimaginable just a few years ago. Unfortunately, some things can not be overcome by technology, so, in addition to status updates and family pictures, we also get the latest evolution of chain letters. I have always hated chain letters because they function off of guilt. That's why, even when I see a message with a good cause, I won't repost it if it motivates by guilt.
You've seen the posts. Some urge you to repost if you are a caring person, implying that you are a jerk or an idiot if you won't spread their pet message. Other posts fall in the category of slactivisism--you know the kind, repost this or a child won't get her last wish. Of course, you also see the traditional chain letter--share this and you will have good luck, don't share this and you will have bad luck. I find these especially offensive when the originator tries to attribute their message to God--as if He hasn't been misrepresented enough.
To alieviate my own frustrations with these ridiculous posts, I created a few with my own sarcastic spin. Share them on facebook or all of your skin will melt off like that guy in Raiders of the Lost Ark.
