Editor's note: This post is part of the Overheard on CNN.com series, a regular feature that examines interesting comments and thought-provoking conversations posted by the community.
Some of the most interesting comments today came from a story about Donald Trump calling Jon Huntsman and Ron Paul "joke candidates" after they opted not to attend the presidential forum he's moderating in December. Readers thought the whole situation seemed pretty bizarre.
"This is absurd," wrote commenter mdn. "A real estate mogul, who has been bankrupt more than once, is hosting a presidential debate? Only the Republicans could think of this. This sort of thing diminishes the Republicans and the electoral process. Thankfully Paul and Hunstman recognize that and have stepped back. True that they don't have a real chance of becoming president, but they do elevate the discussion. How does Don Thump, who endorsed Obama in '08, get this kind of street cred with the Republicans?"
Many made reality TV allusions. Rudy NYC wrote:
"I wonder if everyone will sit around a big board room sized conference table with Trump at the head. You know, sort of like they do on Trump's reality show. (I never watch it. I think four people trying make 4-foot-tall cakes is more interesting.) This debate could secretly be a model for an upcoming new reality show of his, 'The Candidate.' "
tigerakabj also lampooned Trump's projects: "With Cain out, it's time to name the GOP primary into 'The Presidential Apprentice Show,' starring Donald 'Where's your birth certificate?' Trump with the supporting cast Uncle Rush 'Oxycontin' Limbaugh, Sarah 'Mama Grizzly' Palin, and Cousin Sean 'I Never Lie' Hannity. The candidates can win the game if they can placate the hosts' egos and provide an extra path for them to make a quick buck at everybody's expense. If they can't pull their weight, 'They're fired!' "
But of course, Trump had some defenders who said that maybe this guy has a point after all.
Jason: "Like him or not, Trump is another guy telling it like it is. Paul and Huntsman have no chance of winning. Paul is somewhat of a wack-job and could never be elected as president. While he has some solid positions, they are marginalized by his crazy opinions on so many other issues. Huntsman has a great grasp of foreign policy, but his opinions differ too much from the Republican base to win a national election. Frankly the fact that McCain was the Republican candidate is probably the reason Obama won. McMain was too far off the Republicans' base positions to get them interested. I think Gingrich, while not perfect on every issue, has solutions to a number of our nations problems."
This story really had people chatting, but there were other topics people wanted to discuss. We spotted interesting comments on stories about technology and space.
We posted earlier today about planned cuts at the U.S. Postal Service due in large part to changing technology and Internet innovations such as e-mail. But it turns out e-mail isn't immune from change, either. One company seeks to ban all e-mail in the office, asking employees to use phone calls, instant messaging and face-to-face communication instead. Our commenters were eager to discuss their love-hate relationships with their inbox. Some would be eager to ditch their e-mails.
"I fully approve," said Blackadder23. "The fewer ways people have to contact me at work, the less work I have to do. I wish I could create a total news blackout and catch up on some sleep."
There were also a lot of readers who said they actually really like all the e-mails they get.
"While the volume of frivolous e-mail gets a little ridiculous, banning it is even more ridiculous," said james1095. "I far prefer to get an email from someone over a phone call or cubicle visit. With the e-mail, I have an instant record of the information I can sort and refer back to. With other methods, I have to take the time to write it down elsewhere or it risks getting buried and forgotten. " JoeySz agreed:
"Sounds like maybe they need a spam filter and a new CEO. E-mail is an invaluable asynchronous queue for human workflow tasks, with built-in audit trails, prioritization, mass distribution, etc. It is fully complementary to face-to-face or telephone contact, as well as instant messaging. All have their purpose, and all were adopted for their unique value. I see approximately 0% of companies following in these footsteps."
citizen782: "I don't see the value in keeping an IM client open all day for others to interrupt me through. That would result in much greater productivity loss than interoffice e-mail. It's like someone coming through the office door and demanding attention while I'm in the middle of something more important."
NASA scientists say the Kepler mission has uncovered its first confirmed planet in the "habitable zone" around a star. In other words, it could have water, sparking a great series of discussions about what that might mean for humanity.
We featured some of the conversations on the Light Years blog, including this exchange about whether water really means life:
Edward: "The whole point of this is not whether we are going to get there. It is so people know that mathematically we are most likely not alone. So the more planets with possible water gets closer to proving that point."
nsr007: "You assume that other life forms need water to survive just because the ones on Earth do."
