Those screens arrayed across your browser are called windows for a reason: The Internet should open up new perspectives on the world. But with the rise of personalized Google searches and Facebook filters, are the Web’s windows threatening to become mirrors? Some call the Internet an “echo chamber,” arguing that it endlessly repeats our own assumptions back to us. And extremists who might temper their views in a crowd can instead reach out and reinforce each other online.

American democracy thrives on debate and conversation. Does an Internet that cloisters us in ideological cocoons hurt our political life? Or are the Web’s skeptics just the latest in a long line of alarmists who don’t understand how technology is transforming civic discourse for the better? Optimists cheer the way social media and blogs have broadened our horizons beyond a handful of news networks. They insist that personalization enriches (but does not replace) a responsible media diet and that chance still rules the Web.

On April 17, four writers and cyber-philosophers will cross swords over these issues at the next Slate/Intelligence Squared U.S. live debate. We’d like to invite you to attend—we’re offering Slate readers a 30 percent discount on tickets (see below)—and we hope you will use the comments section of this article to submit questions for the debaters. We’ll pick the most interesting one and moderator John Donvan will ask it at the event. Be sure to include your full name and hometown with your question.

The motion for the debate is “When it comes to politics, the Internet is closing our minds.” Eli Pariser, former MoveOn.org Board President and author of The Filter Bubble, will join chair of the University of Virginia’s media studies department and The Googlization of Everything author Siva Vaidhyanathan to argue for the motion. Internet scholar and The Net Delusion author Evgeny Morozov will team up with Jacob Weisberg, chairman and editor-in-chief of The Slate Group, to dispute the motion.
