Pinterest

Pinterest is a social network site that is particularly popular with women, but not so popular with the "geek crowd" (and hence doesn't get the tech-press notice of Twitter or Facebook). It lets users "pin" items to the virtual wall, such as pictures. It has announced an API for developers to interface with the site, but it appears to be targeted primarily at big corporate brands (social networking sites always do seem to end up being more about branding and marketing and corporate stuff than about actual social networking between individuals not trying to sell stuff).
