If there's one thing that Zuckerberg hates, it's Instagram. Actually I'm pretty sure he's not the least vengeful fellow in the bunch, but at the moment it appears that one of the groups Facebook is about to take on is, indeed, the photo filtering group itself. If you're a frequenter of Facebook, and if you're reading this article I must assume that you are, you know that one of the most popular activities on the social networking site is sharing photos. Over the past couple of years since the mobile smartphone device really started to pick up, these photos have become more and more prevalent as well as more and more skillfully shot - this depends entirely on who your friends are, of course. One thing that I, the people I know, and I'm sure you have noticed is the upturn of photos with odd filters having been put over them. Facebook sees this trend and knows.
