This looks like a feature that LnkedIn could incorporate if it ends up being useful. From the candidate's standpoint it's a lot of duplicative work because much of this info is already on LI.
Also, for the tech industry, isn't it always assumed that a tech candidate is open to a better job whether or not it's obvious on the LI account. So I don't know how useful it is to keep your own employer from looking. If your employer believes that at any given time 80% of its workforce is vulnerable to turn over I think it would probably treat it's workforce better. Would Zynga have treated it's programmers better if it knew that many of them were ready to bolt?
