The CNN Daily Mash-up is a roundup of some of the most interesting, surprising, curious, poignant or significant items to appear on CNN.com in the past 24 hours. We top it with a collection of the day's most striking photographs from around the world.
CNN tech reporter John D. Sutter writes, "Wasn't this supposed to be the 'Twitter Olympics,' where everyone rejoiced in the digital-era magic of hearing directly from the world's best athletes and scrolling through a global, real-time conversation about what must be the planet's most 'Kumbaya'-like sporting event?"
Well, yes. But things don't always go as planned, as evidenced by some athletes' questionable tweets and the groundswell of digital criticism for NBC's coverage of the Games.
CNN readers have at least as many opinions about Twitter as they have about the Games.

It's the thing the younger generation does not get....yet. They are eons ahead of us old timers with the technology...no 2 ways about it. But they don't yet understand the ramifications of the technology. Nothing happens in a vacuum. There are consequences for not understanding the public nature of all this technology. It's one thing to know how to drive a car.......quite another to understand "the rules of the road" however.

Eclectic author Gore Vidal died Tuesday night at 86, leaving behind a body of work that chronicled American culture with a clear and often critical eye. Throughout his life, Vidal didn't shy away from controversy - either actively courting it or inviting it through his acerbic one-liners.
I've had hard targets in my lifetime, I've taken on general superstitions, but that's what writers do. So I certainly, wouldn't have changed my modus vivendi one bit.

Crop circles are very interesting anomolies. The manmade, err, personmade ones are really intricate works of art. They've really come a long way since those two old men began making them decades ago.
The Jewish ole ladies are more artistic, don't ya think?lol
I think they might be dry air wind tunnels- instead of tornato's. Or a student project. They are actually too geometric to be mother nature.
Please elucidate on these crop circles Philip.
Actually, whether made by man or not, there amazing pieces of art.
Hope these comments to myself aren't reflective of the norm; musta rubbed the ring leader the wrong way.
Later

Everyone falls prey to them.

It would be funny if romney's horse lost. So he wouldn't feel so alone in November.

Me too.
So your going to vote?
