Well it works for some people. For instance, a friend just told me earlier today that he got the job I forwarded to him from one recruiter that contacted me through linkedin. Also, you don't see the connections between people you didn't know met each other. I find it useful despite all the issues that they have. Disclaimer: I don't live in USA and I suspect the experience is quite different over there.
