Facebook made some changes yesterday which resulted in the following cartoons being shared ad nauseum on Facebook. In a week, these will be forgotten which leads me into some other thoughts I’ve been having around how Twitter, Tumblr and Facebook particularly have made social sharing so easy to do that there is almost zero friction when it comes to spreading information. The result is that memes are created and killed in rapid time. Rickrolling lasted for a year or more, but today’s memes are, well, today’s memes. There’s a new one tomorrow.
