The concept behind Pinterest is deceptively simple. Users employ a "bookmarklet" button installed in their browser to pin images to virtual boards, usually according to a particular theme or purpose. Each image is backed by a click through link leading to the web page where it was discovered. Users can also check out boards created by others and "like," "repin" or comment on what they find. Simple hasn't hurt Pinterest, though in fact, it's half the appeal. Pinterest is easy to use, easy to browse and offers such a wide range of content that almost everyone can find something to enjoy.
