Github has become the number one place to show of your portfolio. Half of job postings these days encourage you to include a link to your GitHub profile.
Even for totally private repos, where popularity is not a factor, I continue to turn to Github because the UIs for both Bitbucket and GitLab continue to stand in the way of me easily getting shit done.
If I want to see someone's work, and they provide a URL, I'm interested in the content, not the identity of the service it's hosted on. Gee, this sounds familiar...
