When I link out these days, it's often the follow-up to actually meeting someone. So anyone I've met in person is much more likely to get a positive response to a link request. You've got to press the flesh.
So the next stage of internet evolution is when we go full circle, and get doorstep link requests: press-the-flesh spam.
