If your Instagram (or Twitter or Facebook) feed is full of photos of yourself, whose feed is it really? Aside from the now-ubiquitous “selfies” that litter social media, who is taking these photos of you? If you’re the (purported) author of your feed, the content should be through your eyes, not through someone else’s looking back at you.
Social media platforms are little more than tools for self-aggrandization in one form or another, but the “look at me” culture is one form that is more unfortunate than others. It’s much more interesting if people with unique perspectives would use their social media platforms to say, “look at this”, “look at that”, and “look at them” rather than always “look at me”.
