Pinterest: it’s the latest social media trend populated primarily by women in their 20s, 30s and 40s – it’s described as addicting – and the numbers prove this new social media platform is growing by leaps and bounds. According to Mashable, 70 percent of pinners are female, and are highly engaged, with stats reporting 3.3 million users logging more than 421 million page views. Just ask any 20-40-something female…if you can get her to stop pinning.
