Big fan of Pinterest? You’ve got to love this new responsive WordPress theme – Pinboard. It features an auto stacking layout with infinite scroll as seen on the Pinterest desktop site. If you are unfamilar with the term “infinite scroll”, it means that new posts are loaded automatically when you hit to the bottom of the page. The stacking layout works perfectly and responsively on any resolution using a desktop or mobile devices such as iPad, iPhone, Blackberry, and Android. It also includes multisite integration which enables users can signup and post. It works on both single WordPress or multisite installation.
