A couple of people have pointed out my phrase "non-members extracted from my address book"... Perhaps this should more accurately have been "possibly" extracted from my address book. I'm a friend of Tom, Jerry, and Spike. We all have each others' email addresses in our address books. We're all LinkedIn members apart from Spike. Tom and Jerry both upload their address books to LinkedIn, but I don't. LinkedIn doesn't require a wizard to work out that austinjp may know non-member Spike. They simply have to display Spike in a mixed-list of members and non-members and wait for me to click him. They even differentiate non-members from members, but too subtly, and all it takes is one mistaken click.
