Social networks may have first been invented to solve a problem revolving around communication, yet they have since evolved to be much more niche such as Updog. Updog may be described as "a revolutionary communications platform for the connected and powerful," but that's simply where the joke starts. Those unfamiliar with the term 'updog' are in over their head, those who are will enjoy the treat.
Essentially, people can use the Updog website to prank friends and family with the 'updog' joke. Ed Zitron perfectly shows how that is possible, over and over again, "Please do not call me a dog when I request information sent via Updog." Simple yet clever, Updog is a site that might not ever get old.
