Thanks a lot for your insights. I fully agree, that the setup necessary for efficient recruiting is the one LinkedIn serves, I will say, that I think that exactly this is what causes the trouble to me because it pulls value away from the individuals to recruiters and larger cooperations. Maybe I'm wrong about this, and people primarily want the public CV being found by recruiters thing and what I imagine is like a more niche kind of thing not applicable to a large group of people as a career network.
I might be too idealistic, but I imagine a community, that is more on eye level with everyone not hiding behind long track records. I find it desirable to be more transparent and make advancement easier. Otherwise see both over filtering and valuable connections falling through the grid because one doesn't have the ivy league school and fang experience in his profile.
