That is the rub with most of this 'data'. Each one by itself it is nearly meaningless. But tossed together it creates a much more interesting thing to use. Like my DOB is borderline useless. But combined with a few other random bits of info and you can target me nearly exactly. The amount of random info is not much at all either. Add in a metric like gets depressed/excited by, and the intrusion gets even deeper.
