I used to rave about LinkedIn because of that feature, and now I don't see it. It used to give you information like how many people are checking out your profile, what industry they're in, and how many times your name or your site has been pinged in the world wide of web. And now nothing! That was one of the features that made me visit LinkedIn often and become more proactive about my account. They recently did some updates on Friday night. Hope they're going to bring that feature back.
