Understanding Pinterest: A social media ‘outsider’ or marketing gem?

Think ‘Pinterest’ and your mind probably wanders to images of wedding venues, luxury couches and recipe ideas. Although it is a visually powerful platform, it does not traditionally scream ‘post your ad here’ and unlike other social networks it is often considered to be a bit of an outsider.
However, with more than 200 million active ‘pinners’ worldwide using the site on a monthly basis perhaps it is not the social media introvert marketers might think it is.
