I’ve just classed Pinterest as social networking, but to be strictly accurate it’s a social bookmarking site. Bear with me. Such sites, like Reddit and Stumbleupon, are well-established, enabling like-minded people to discover new websites in areas that interest them. Pinterest came along in 2010 and the clue to its philosophy lies in the name. Pinterest is a virtual pinboard – a platform for sharing pictures and videos. Its uniqueness, its appeal, and the key to its success, lie in the way it showcases these categories.
