The Pinterest thing is kinda justified though:

Continuing a long-standing trend, women use Pinterest at much higher rates than men. Nearly half of online women use the virtual pinboard (45%), more than double the share of online men (17%) who do so.
There should be nothing at all wrong with saying in public to people of any gender that Pinterest is a very female-skewing website.
It’s not about saying that Pinterest is female-heavy - it’s about the assumption that everyone is male / has a wife/girlfriend. Even though everyone was male, this contributes to the feeling of ostracization.
Oh god my eyes.
