I read a lot of comments here and everybody's "Github this, Github that". It's 4 years since Github was bought by Microsoft, so here is the breaking news:

Github IS Microsoft.

So every time you read "Github" invoke that part of your brain that uses "ReplaceString" function and read "Microsoft" instead.

"Sing in with Microsoft" - do I really want to use that on "this obscure site" knowing that if my account gets suspended/banned, Microsoft won't care at all? That's the real question.
