For something more serious, check out Weingarten's thought-provoking feature piece about dead children — "Fatal Distraction", http://articles.washingtonpost.com/2009-03-08/news/36840402_... . His story does a good job of (1) telling stories about tragic accidents where children were forgotten in the back of cars and died; (2) showing that the key factor in whether or not the parents were prosecuted was not the facts of the situation but instead which prosecutor's district the deaths occurred in; (3) finding a surprising explanation for the increase in these accidents — rear-facing car seats. Given the subject matter, it's neither smug nor glib, and so you might prefer it to his subway violin story.

You always need to adapt your art to the medium and provide contrast. To do otherwise is to argue against reality. Your average run-of-the-mill street performer is always going to get more attention than Joshua Bell will on the street.
