HN on Linkedin

The groups are less useful when large, but when small they can offer a way to locate people who could be perfect for you (and you for them).

Regarding the group, I'd love to join it but I don't have 20 karma points on HN.
Also, answering questions relevant to your interest area on LinkedIn is a good way to make contact with people who have problems they are trying to solve.
But I don't need another badge, another forum for questions, and another list.
Which is a shame because I think the a Hacker News LinkedIn group makes sense.
I've noticed that drift, and I'm not on FB. I think that's not where they need to go.
