Yes. I mean, I still think it's kind of odd to have an entire Instagram feed of just pictures of yourself in front of code. But somehow Instagram's algorithm decided to show me tons of these types of pictures in the "Explore" tab.
A huge amount were, like another commenter mentioned, girls in yoga pants or short shorts posing with Sublime Text in the background. And they're hugely popular.
In no way do I think the original poster's feed is like this. She seems genuinely interested in coding. It just led me into this entire apparent subculture of this type of thing.
