Gitlab often comes up in these discussions. Ok, it comes up every time. Several times in the past I've went and checked it out and it seems interesting except...I couldn't find any actual projects from the main gitlab.com page, aside from the gitlab CE repo itself. So thanks for posting that link!
I have to wonder why it's not more prominent. And where's the search to find repos? I regularly find useful repos on github by searching for them. Discoverability is important to me.
