Upon reading the article, it seems that the father does not, in fact, find any help through Twitter. "Word of missing girl spreads somewhat quickly through Twitter" would be more accurate (and less interesting).
Well sure, since it's about Twitter. I just don't know if you can extrapolate and say Twitter will be this great platform for finding lost children.
I also suspect a real Amber Alert would be far more effective, since it notifies millions of people in the same region as the missing child, not a few thousand people scattered across the globe, most of whom who have no chance of helping.
