Editor's note: We're listening to you. Every day, we spot thought-provoking comments from readers. What follows is a look at some of the most talked-about stories of the day.

Mitt Romney has announced his pick for running mate in the 2012 election: U.S. Rep. Paul Ryan of Wisconsin. Readers have mixed feelings about him, but they've definitely been talking. The next five stories are all about Ryan.

When the news initially broke, many readers argued about what it means. All seemed to agree that the game was suddenly a little more interesting. Several iReporters, like Mark Ivy of Farmersburg, Indiana, said they felt this choice was the right one.

"As the news began to trickle out late last night, and turn into a cascading waterfall, that House Budget Committee chairman and Wisconsin Rep. Paul Ryan had been selected by Mitt Romney as the person to be his running mate and the next vice president of the United States, I began to read and research all I could on the congressman. That study led me to the conclusion that this morning as Romney was announcing his choice of Ryan, Romney had indeed made the correct decision. That decision puts the question of fiscal responsibility and a right direction for the country squarely on the table."

And Matt Sky  of New York said having Ryan around changes the conversation.

"Adding Paul Ryan to Mitt Romney's ticket changes this election from simply being a referendum on Obama into a core philosophical debate about the differences between conservatism and liberalism. Wisconsin Rep. Paul Ryan is an exciting figure for many Republicans, but also represents the core divisions between the parties in a way that could also rally more Democrats behind Obama. We have very articulate, intelligent candidates across the board, so I think we can expect a fascinating, very unique election year, not about personality or popularity points, but one of substance."

On CNN's Facebook page, readers were critical of Ryan's economic vision, which was the subject of an opinion article by Donna Brazile. But some were in support.

Chris Perrin: Ryan's budget would destroy the middle class and the working poor. We would all become serfs to the rich. Now that is class warfare if I've ever seen it.

Colleen Warman Meyer: "Does anyone find it ironic that democrats keep saying Ryan's budget proposal is too radical when the dems in power haven't bothered to even pass a budget in years? I think a little radical is better than nothing. Our national belt has needed a lot of tightening anyway."

Ralph Quaas: All this means is money for Republican pockets and not a dime for seniors and the needy.

Charlotte Booth Davidson: "Can anybody ANYBODY tell me why I should vote for Obama? And not because of Romney/Ryan. Convince me how our country is better off then three years ago?!!! Please!"

Michael Sercu: "Ryan and Romney declared: 'We do not want our kids stuck with trillions of dollars in debt.' The bad news: They want other people's kids stuck with that debt."

CNN.com commenters also had plenty to say.

1. Romney's pick of Ryan as his running mate energizes conservatives, opponents

This reader said they weren't originally planning to vote, but decided to do so. They were one of many who alluded to author Ayn Rand, author of the influential and controversial novel "Atlas Shrugged." Ryan has said conflicting things about his stance on Rand's work.

aabbccddee: "Thanks Romney, by choosing Paul Ryan you helped me to decide that I'm voting for Obama. The last thing we need is a conservative Ayn Randian objectivist in the White House."

THX1953: "Ha! Like your vote wasn't already cast!"

aabbccddee: "It wasn't. I dislike Obama's conservative policies so I was going to sit out this election. To me, Romney and Obama are two of the same. Romney's choice of Ryan has awoken me from my apathy."

Another reader said they were glad that a person with vigor was joining the race. FULL POST
