Funny how the QR Code Virus spreads - now you can already see MS Spaces blogs with QR Codes;)
The "What is this?" (Was ist das?) we already use for some time (here and here) tells us this:

Scan this QR code with your mobile phone to jump to this person's mobile Spaces. QR codes contain URL information that you can scan with most Japanese mobile phones.

Least Common Denominator (LCD) is the coding style that authors need to resort to when adaptation is not a possibility for any reason. In those cases, any HTTP client which requests the document will receive the same HTTP headers, the same mark-up and the same pictures in terms of size and format.

While LCD is the most widely adopted approach for the creation of internet web sites, device fragmentation prevents LCD from being equally effective on the mobile web. Choosing a default experience that does not take device features into consideration is bound to deliver a poor user experience on most devices.

We couldn't agree more.

PS: If you just want to have a nice mobile version without getting deep into mobile rendering, you definitely should try out: feed2mobile. It only needs an RSS-feed to get your own mobile version and a personal QR Code too.

I just discovered the QR Code-Sandwiches from automeal. And then I tried to read the QR Code - which worked perfectly. The only problem I had: It's all in japanese and my mobile phone still doesn't display japanese characters (the psiloc software failed to my great regret).

After the few indications out of the text, this could be the text message encoded:

ポークテリーヌとレンコンのピックルス、南瓜と紫キャベツの57*57*114モジュールサンド

which is:

a pork terrine and lotus root pickels, pumpkin and violet cabbage 57*57*114 module sandwich.

W3C Workshop on the Mobile Web in Developing Countries

The "Digital Divide" is defined as the gap between those with regular, effective access and ability to use digital technologies and those without. An important step in the direction of filling this gap has been the deployment of mobile networks all around the world. For example, as of today, more than 80% of the world's population is covered by GSM, and more than 2 billions of people own a mobile phone (source: World Bank). With one million additional people newly subscribed every day, it is expected that by the end of 2010, almost 4 billions will have a mobile phone.

However, even if accessing phone services is very important, the gap will be more completely filled when access to a higher level of information technologies will be widespread. Now, with the availability of high speed mobile data networks, and the appearance of increasingly-affordable web-enabled phones, one can imagine that the potential to help bridge of the divide has increased, in that people with access to a mobile phone would be able to access the Internet and the Web. However, it is fundamental to understand the needs and the expectations of the people, and the specific challenges and issues of accessing the Web from a mobile phone as a primary and often sole platform, so that the potential of resolving the gap becomes reality.

Interesting initiative! On this blog there are quite a lot of comments coming from people from the so-called emerging markets. So I guess, we can say, that we definitely see the potential.
