I know I'm old, but I now find LinkedIn to be my favorite social media site, and I'll explain why.

Skin in the game. Yes, it's full of fluffy sounding things, but with a little patience and reading between lines, it's extremely valuable and here's why:

Overwhelmingly most of the time -- when someone posts anything there -- it has the potential to directly quickly improve, or more importantly destroy, their own LIVELIHOOD. It feels like the opposite, but making the choice to post there is a huge risk.

Now, that might come with fluff, of course -- but in a way you could reasonably argue it is the REALEST social media site of them all.
