Pinterest is among the social media websites and apps that have been struggling with an erosion of its user base, coming on top of a difficult ad market. Nonetheless, some analysis in Motley Fool and Bezinga points to a potentially positive leadership change at the company and a pattern of increasing revenue per user as reasons to be bullish. With an audience that leans female (58% of its website audience in September) and a strong focus on topics like fashion, Pinterest captures a consumer audience with strong advertiser appeal.
