Why on Mobile Platform, the context is king, not the data

Today, I get a email from Academia.edu network about some interesting resources, so I collect them and post here for everyone like build a social network about tourism on Mobile Platform.
Just like Instagram, which can be very useful for PR and business can communicate more visually. A community app about tourism (Vietnam has many interesting places)
Some people like travel as adventure , can benefit from community. Not just like the traditional web, you create the content and consume the content. The data and the context is king on mobile platform.
The personal computing is really go with you everywhere, the cloud at the backend process the data and recommend more personalized information with the context around you (here is the time and place)
context for mobile app
Content is the king, I disagree. We will never understand our users as well as you until we get true information (metadata) about the context of users.
