EFFECT
As expected, I immediately got several likes when I posted the image around 2:00 PM on Friday. These were from the usual people who like my profile pictures. After three days though, the picture gathered 36 likes total and a few comments, including several likes from people who don't normally interact with me on Facebook. This profile picture is now the most liked profile picture of mine, which was rather surprising.
There aren't any thematic similarities between this and the next most liked profile pictures (coming in at 25 likes a piece). For the picture of me, I simply thought it was a decent image that one of my friends took and decided to use it. For the illustration, I had finally finished a proper illustration for once and used it as my profile picture because I was relatively proud of it. My new profile picture was much more deliberate and clear with symbolism, and I suppose that was what put it ahead. It's also possible that people just reacted to the joke.
