The above poster was saying there is a subculture of people who, in order to feel superior, conspicuously avoid posting on Instagram about a sunset. This is an absurd characterization. There is no place in the galaxy in which it is conspicuous to not post beautiful things to Instagram. I have no judgments for users of Instagram, but a pocket full of confusion for someone who assigns a motive and subculture to everyone who doesn't live their lives exactly the way they do. It's provincial and sad, ironically so, considering that in context, that these people are documenting the travels to a foreign land.
