@lightweight It wasn't as big of a steaming pile until after Microsoft acquired it. After the acquisition, headhunting and advertising both exploded. You're going to see (and already are) the same on GitHub.
@etbe @lightweight When LinkedIn first started it was about (business/professional) networking (at least that was what they said). Sure networking can aid in job hunting by allowing you to advertise yourself, but that is a pull relationship. Nowadays LinkedIn is all about pushing.
@lwriemen @lightweight maybe it depends on what you are trying to do. I find myself with less money than I want, I check my LinkedIn updates regularly with phone notifications on, a couple of weeks later I have no money problems. Works for me.
