Quote of the day: How can users trust Yahoo?

Rep. Brad Sherman, D-Calif., asked Yahoo spokesman and general counsel Michael Callahan whether the NSA has access to the e-mail of private American citizens. A user of Yahoo's e-mail service, Sherman became frustrated as Callahan avoided giving a direct answer and asked, "How am I supposed to be a user of Yahoo if you won't tell me whether I can rely on privacy?"

The debate came during the House sub-committee's hearing on Internet security and censorship in China. Click here for video of the exchange.
