Last November, Daniel Appelquist made a post that described an extension of "Web 2.0" thinking into the world of mobile devices - "Mobile 2.0." [Link]

When I traveled to Spain on business last month, I took pictures with my camera phone which were automatically uploaded to a photo sharing service as I took them using a photo upload application that I had downloaded over the mobile Web. My beautiful wife and kids were able to track my trip in pictures by checking back with the photo sharing site as I traveled and no PC was involved on my end. A downloaded mapping application on my phone allowed me to easily find my way from the city of Gigón to Bilbao, and I was able to access Wikipedia entries on cities I visited to find background information when I needed it. A downloaded mobile IM client embedded on my email device allowed me to keep in touch with colleagues and friends. Mobile 2.0 is not “the Future.” it is services that already exist all around us. These services are maturing at an amazing rate and what they are doing is effectively knitting together Web 2.0 with the mobile platform to create something new: a new class of services that leverage mobility but are as easy to use and ubiquitous as the Web is today. These services point the way forward for the mobile data industry.
