There was a lot of outrage among a small group of LinkedIn users who said they had been stalked, in part via LinkedIn, and this feature should eliminate that issue for them. I read many of these stories on the LI group Rihtar formed, and some were heartbreaking. Delighted LI finally put this into place -- although like everyone here, unsure why it took so long since most social networks have this capability. I can't imagine being stalked by a stranger through a business networking site. Whereas I could and would leave Facebook, leaving LI would damage my ability to do my job. And I'd resent it, as it's the person who's not in the wrong who's being penalized by being forced to leave.
