Backchannel published A Teenager’s View on Social Media. It's a kinda interesting look at what one 19 year-old's social network uses to keep in touch. He followed it up with What Teens Really Think About YouTube, Google+, Reddit and Other Social Media. As he said, neither is a statistical study or an attempt to describe what every teen uses, but it's a nice survey of the options. There's been some backlash, the faults are described in An Old Fogey’s Analysis of a Teenager’s View on Social Media.
On the other end, Ars Technical wrote about Ars’ small taste of no-tech travel. A couple took a weekend trip (by train) and didn't use any tech for one whole entire day but did use it the next day and compared the results. Basically as you'd expect.
On the really high tech side, Microsoft’s new interface: FREAKING HOLOGRAMS. They demo'ed a new device that's apparently going to be available "in the same timeframe as Windows 10" that's a combination Oculus Rift and Kinect. It's goggles you wear, that can project images a la augmented reality, but that you can also interact with a la Kinect. Ars Technica, Re/code, and Yahoo Tech all got a hands-on demo and really liked it. The Verge says, Minecraft — more than anything else — could make HoloLens a hit.
