Have you ever wondered why the photos that you share on Facebook or Instagram don't get as many likes as other people? Well, thanks to the work of some researchers at MIT's illustrious Computer Science and Artificial Intelligence Lab (CSAIL), there is now a computer algorithm can now tell you how popular your photos will be -- and more importantly, how to make them more popular. You will be unsurprised to hear that the algorithm discovered that sex definitely sells -- posing in a swimsuit or miniskirt virtually guarantees a bunch of likes/shares. Interestingly, the software also found that bold colors such as red, blue, yellow, and pink also garner more likes.
