I didn't downvote, but... It's actually pretty irritating that discussion of any project not hosted on GH gets "Why not Github?" question, every single f-ing time.
I hope this will end, together with LinkedIn invites.
It was more of a genuine question than of a criticism. There are obvious advantages about having a public repository if one is distributing the source code. But there might be disadvantages too, even as little as the setup time. I should have made the question more explicit.
