If only that applied to everyone. Most people will get ten crappy notifications with one good one and go "Oh, well, not too bad." I think I used the 'People You May Know' feature a bit when I first joined but, as time went on, it really just became "This one guy who once worked at the same place as you and maybe knows someone you know". These algorithms are very smart and that's their problem - they overestimate the number of connections an average person makes.
