If you’re online for more than 30 hours of non-work surfing every week, experience withdrawal symptoms and find your relationships with friends, family and coworkers suffering, you might be an Internet addict. This video, hosted by Kimberly S. Young, introduces netaddiction.com. Young is the  founder of the Center for Internet Addiction Recovery. Take their Internet addiction test to see where your own usage rates.

Today’s Word of the Day, K-scale, or “Korean scale,” is a checklist used for diagnosing and evaluating Internet addiction.

Two weeks and less than 10,000 lines of code result in this demonstration of a starfighter action game on an iPhone that takes advantage of the device’s accelerometer, touch screen and high contrast display. This is a great use of the interface and should inspire some creative thinking the software development community.

My immediate thought upon seeing Steve Forstall’s demo is that there could be a lot of flying iPhones, similar to the stories we’ve heard about the Wiimote. Remember those videos of plasma screens when the Wii debuted?

Now just imagine it’s a device that costs more than $500 direct from Apple in the U.S. and often much more than that in Europe.

That being said, I’m excited to see how software designers take advantage of that new Apple iPhone SDK.

That and Spore. Given more than two weeks to work on this game, I think this could be a killer gaming app for the device.
