In addition, I'm not a huge fan of linkedin either. There are no guarantees to it. One is that most of what's on there is hard to check and linkedin endorsements are just unreal to start with.
I know people who just endorse each other for random things. I have endorsements from people who I have never worked with for technologies I have never worked with.
So in the end — Github or similar wins. Allows me to see their code (and contributions), and that's what matters. For the rest (compatibility on a social level), there are interviews and probation.
