Don't Follow

Please don't follow me on social networks. It's weird, kind of creepy, and I just don't like it. This is a program to detect duplicates. Why in the world would you want to hear about what we are doing on Twitter? What would we even talk about? "Oh boy, just recieved a telegram that somebody found two copies of their research paper in their documents folder. Wowwee!". I would unsubscribe from me. These social links don't do anything. I really don't think anybody is reading this far down, but if you are and feel the need to follow something you should follow this cat named Van Gogh on instagram. Just click that Instagram logo below!
