Aaron Wilson writes: "U.S. Presidential hopeful Mitt Romney kicks off YouTube's "You Choose Spotlight" by posting an informal video of himself. In the clip he calls for feedback videos from the YouTube community. "What do you believe is America's single greatest challenge?" Mitt says, "And what would you do to address it?" While the YouTube community shoots back with mixed responses regarding political issues, there is general enthusiasm about a presidential candidate embracing the Internet community at large."
