Skype a few years ago as the hottest messaging client around, it was eventually purchased and then experienced a decline in its user base. People traditionally have used Skype for making free or very cheap voice calls to their friends and family. Today Skype generated a lot of interested with the release of its iPhone application, which allows user to make free calls to other users from their iphone.

Here is a video the show my initial review of the app.

Will the Skype iPhone app get you to use Skype more?

I have talked about QR Codes a few times in the past, mainly because I see them as a great opportunity to bridge the physical and digital worlds.  For a quick refresher QR codes are two dimensional bar codes that can be printed on anything from a packing slip to a movie poster. These codes serve as a portal to some type of digital action: Web site, video, text message, and even a phone call.

Here is a video I did to help explain QR codes and to review one of the QR code readers available for the iPhone:

So if you have a QR code reader then they are pretty simple right? The problem is not everyone has a QR code reader and the bigger issue is that most people in the U.S. don’t know what QR codes are.  QR codes and other 2D bar codes are very popular outside of the U.S., especially in Japan. The opportunity with QR codes is that they are low cost. Most companies have Web sites that are used in their marketing efforts so they are already shelling out the cash to create them. The QR code can simply serve as a free method of extending that site into the physical world. Since QR codes are black and white they can easily be added to print materials with no additional cost. They are also free to create and the process only takes about a minute.

This sounds good right? It is, we are stuck with the problem that people don’t know what they are. So that leads me to my experiment.  I will be at South By South West Interactive next week and while I am there, I am going to conduct my own QR code experiment.

I realized that I have created a super dorky t-shirt, but I am interested to see the response. I will report back after SXSW to let you all know what I found out.

Social news site Reddit has a very loyal community and can be a great source of information. How does it translate to the iPhone? Is it worth $1.99?
