My posts have even lead to the odd DM conversation with a minor industry "celebrity" or two - Id Software's John Romero and the British tech journalist Jason Bradbury being two recent examples off the top of my head.
I suppose I just wanted to share an example of the platform being used for something other than shameless vanity. It's nice to know that I'm not alone in my weird hobby and there are plenty of others out there. Of course a forum might be a better place to discuss these things, but Instagram is very quick and easy.
That said, even in the retro tech circles there are the girls whose feeds are endless poses with their boobs hanging out holding an N64 controller and somehow have millions of followers...
There are certainly cases where I could see it becoming a real problem, especially for younger people. However, nothing stops you from using the platform for something great! Be the change you want to see in the world.
