Can we just acknowledge just how much of an improvement github is over the olden days? Seriously. And as far as social media websites go, Github is surely one of the most ethical of them all.
Github popularized git in a time when svn and cvs were the standards. Don't forget about those sad, sad times! We are in such a better place now! They also recognized the power of git to completely lower the bar for participating in open source projects.
"Pull requests"? "Forks"? That stuff didn't exist in the mainstream developer imagination. It was fringe. Now it's the default!
And I'm not trying to say that github is the best model or platform or anything like that, I just appreciate how easy it makes it to participate in open source development. It's clean, it's simple, and it works.
GitLab and BitBucket, those are awesome platforms too. But Github struck a chord in a time when people hadn't even heard the melody yet.
I hope the future brings something even better. But I'm still definitely gonna give props to github for holding it down.
