But her sudden rise to popularity is prompting many commentators, even those not usually noted for their interest in light entertainment, to find a deeper meaning in her performance.
"Boyle let me feel ... the meaning of human grace.... She reordered the measure of beauty. And I had no idea until the tears sprang how desperately I need that corrective," said Entertainment Weekly writer Lisa Schwarzbaum.
Robert Canfield, a professor of anthropology at Washington University in St. Louis, Mo., quotes Ms. Schwarzbaum in his blog where he typically comments on Pakistan, Afghanistan, and Iran.

Dr. Canfield says, in response to emailed questions, that Boyle captured "the hopes of a multitude."
Her performance resonates with millions, he says, because "most of us in our heart of hearts have severe doubts about ourselves.
"So when a Susan Boyle appears on stage before a clearly condescending audience in a society that can read class status in every move, the hairdo, the dress, she appears as a loser. And we feel for her. We see how precarious her position is, how vulnerable she is, and we feel for her," he writes in his email.
