Try being a single dude in your 20s/early 30s without some "social proof" when trying to talk to 30 and younger girls. They will immediately think you are a weirdo for not having that proof that you're not some sort of loner. I personally use ig for posting things that give me a little more edge over normal dudes - my Olympic weightlifting progress, my trips snowboarding/surfing, my cute dogs, music festivals/shows that I got to...it's helpful. but I'm not gonna post on there about the new Jenkinsfile that I spent a week crafting to deploy a 10 microservices for a state machine. RIP Google+, the Instagram for geeks.
