Reddit is not social media because it’s not about social interaction, because it’s anonymous. It’s not social if it’s anonymous.
That’s how I think about it. I avoided social media my entire life, even though I was the perfect age all along: xanga/MySpace in middle school, Facebook opened to everyone when I was in high school, Instagram came about when I was traveling/living my adult life in my 20s…but I’m glad I avoided it. Reddit, when I used it, struck me as very different. It’s not about you. It’s about anonymity and news/memes. If that’s social media, all of the internet is social media.
