The  era of 'rock star' advocacy is over.
 The woman largely  responsible for vehicle air bags, Joan Claybrook, who announced last week that  she's stepping down as president of Public Citizen after 27 years at the helm of  the consumer watchdog group founded by Ralph Nader.  No successor at Public  Citizen has been named.
 The consumer movement is  at a crossroads. After becoming a force in the 1960s with Nader's rise to  prominence, it has since struggled to connect with the media and  public.
 "In many ways, there's less of a movement now,"  Claybrook acknowledged. "Now there are specific advocates for specific  issues.
 NADER -  There's so much clutter in the media  marketplace, so much noise from competing interests that it's increasingly  difficult for a nonprofit group to get its message across, much less stir up  sufficient outrage to catalyze political action.  "We used to put out press releases and they'd be  on the evening news," he said. "Now you can't even get them on  cable."
 "The indications are very bad," Nader, 74, said of the  future. "We all thought the Internet would give us a resurgence. The big hope  was that you could band people together quickly and cheaply, but it  hasn't worked out."
 For his part, Nader makes no effort to hide his  frustration. "It's been very difficult holding back the hordes of corporatism,"  he said. "It's become more defensive than offensive, just trying to save what's  been achieved."
 They aren't easy acts to follow. "Nobody will ever  be a rock star again like Ralph Nader," said U.S. PIRG's Mierzwinski,  55.
 The Internet has yet to live up to its potential as an  engine for consumer protection, but it still can.
 Ultimately, it's up to us -- consumers -- to demand  accountability for unsafe products and stronger regulation of businesses, and to  remain engaged with the legislative process.
 This movement was always about  one thing -- you. Isn't that worth fighting  for?
