Initially, LinkedIn was just another site where you could find jobs. It was simple to use, simple to connect with others; it even had some friendly groups with meaningful discussions.
And then it gained monopoly as the “sole” professional network where you could actually land a job. If you are not on LinkedIn now, you are quite invisible in the job market. Recruiters are concentrated there, even if they have to pay extremely high prices for premium accounts. The site is horrible now: a social network in disguise, toxic and boring influencers, and a lot of noise and bloated interface to explore.
When Google decided to close their code.google.com, GitHub filled a void. It was a simple site powered by git (not by svn or CVS), and most of the major open-source projects migrated there. The interface was simple, and everything was perfect. And then something changed.
GitHub UI started to bloat, all kinds of “features” nobody asked for were implemented, and then the site became a SaaS. Now Microsoft hosts the bulk of open-source projects the world has to offer. GitHub has become a monopoly. If you don’t keep your code there, chances are people won’t notice your side projects. This bothers me.
Rant over. I hate internet monopolies.
This could be what you’re looking for. Their main implementation is a gitea fork, but I’ve seen mentions of gitlab as well. Unfortunately I don’t think github would ever consider being compatible, that would just lose them users.
Thanks. There is also a Gitlab issue requesting this feature, which I am tracking.
It needs to reach a polished state before organizations and university adapt it. So something like what you linked probably wont fly.
