It Came From Outer Space
At its launch, Pinterest was immediately labeled as an inherently Feminine social media site in its method, largely, it seems, because its early user base, unlike a lot of other social media communities, was predominantly female. In fact, that's the opposite of most other social media communities. And it wasn't because its captcha service asked "Are you male? (Don't lie.)" and then excluded all the men. Tech sites around the web wrote articles about how men found Pinterest confusing, how the site revealed that stereotypes of the feminine were founded in reality, and went out of their way to reassure men that Pinterest could be used for manly things.
Which is part of why I'm subversively pleased at the idea of a female astronaut using Pinterest to get people excited about science and space exploration.
