As I’m wrapping up my work day I placed a video call to my wife via my tablet PC and Skype, a free VOIP service and even though we’re separated by several time zones and a good portion of the planet, I’m looking at her smiling face and chatting with her while I wait for a ride back to the hotel.

At one point it dawned on me just how amazing and complex technology is. Nevertheless, all good things usually come with asterisk and technology is no exception. In fact, it pays to learn about the basics of online communication before running the risk of having technology put you in a compromising position. For example, have you read about this yet (link may be inactive after 7/26)?
