The creators of Pinterest control the entire website and the way that it has been set up from the very beginning. They made it invitation only at first, so that select users could try it out, and now they have opened it up to all users. In order to join though, users are required to sign up through a twitter account or a facebook account. The founding designer of Pinterest acknowledged that they decided to do this because they "know that Twitter and Facebook can do something that [they] can't do as well" and that it takes away the worry of "a user ever starting out with zero friends" (Lavingia). This fits perfectly with Devoe's assertion that "successful microblogging depends on having an audience" (213). This takes away the anonymity that goes along with many sites on the internet. It enables connection with friends but does not allow for the creation of a separate identity that is not invisible to friends and acquaintances. The creators also set up categories for pin boards to make them easier to find. Recently, they have given users the opportunity to pin videos to their boards. They ultimately control all of the features on the site and they dictate the ways in which users can manipulate the site.
