The lights dim, the orchestra tunes, and the audience is told to "please turn off your cell phones." Except in the "TweetSeats" at Cincinnati Symphony Orchestra concerts in Music Hall. That's where iPhones, Blackberries, and tablets light up and concertgoers start tweeting live along with the music.

"Tweeting the CSO's performance was like attending a members-only social event in the midst of a traditionally formal setting," said tweeter Jennifer Nissenbaum, 35, of Dayton. "I could communicate openly about my reactions to the music, musicians, and conductor–without speaking a word. Plus, I had the opportunity to engage others, and get their reactions to the performance."
