They now added achievements 5 days ago. I have an achievement for having "opened pull requests that have been merged". It really is becoming a social network.
It's just... noise? I assume the average github user is a developer and has closed dozens of PRs in his life.
It's cool to see someone's code is on the mars rover or in the artic storage. I can't care about achievements like "yolo" "galaxy brain" and "pull shark". I don't understand what information that conveys on a code collaboration platform.
