Now that Microsoft's bought out GitHub, I plan on migrating my active projects over to GitLab.com when I get the chance. I actually registered one of the earliest account over there (https://gitlab.com/michael) way back in 2012.
Looking forward to when they eventually get federation support (https://gitlab.com/gitlab-org/gitlab-ee/issues/4517). Gogs and Gitea are investigating this too. Cool to see they're all talking about doing it with ActivityStreams.
