At this pace of innovation, GitHub will soon be a part of the history! GitHub has done a tremendous job with forking and pull requests, but, at least recently, they've acted disorientedly! I hope they get back into shape!
All that I do now that I really enjoy watching what looks like a full on feature battle between GitLab and GitHub going on at this moment. As a guy who uses both (GitLab for my job, GitHub personally), I feel like I'm getting the best of both worlds.
Although, to be perfectly honest, it feels to me like, at this point of the "feature battle", GitLab started embracing and actually improving every single thing I liked about GitHub to the point where I'm questioning my stay on GitHub for personal projects.
