Last September, Pinterest reported that it had reached the milestone of 100 million monthly active users. And while, comparatively, that may not seem like much - Facebook has 1.71 billion MAU - as highlighted by Pew Research, Pinterest usage is actually increasing at a significantly higher rate than most other platforms. While the bigger platforms get more hype, Pinterest has slowly, but surely, been establishing their place in the social sphere, with ambitions to be generating $2.8 billion in annual revenue by 2018.
