Startup Idea : aPage (Integrated Profile

Smart Phones are essentially computers. So why put all your personal data in the hands of some company(Facebook)? Why not develop an app that allows users to connect there box/dropbox/drive account and help them pick a website interface, upload a photo, add content, and store it all on the cloud service they connected. Then the app will check other people who have the app in your contacts and sync their aPage into your phone book. For security you could integrate it so that only people who have your number and you have their's can only see your page. If they want anyone who has your number to be able to access it then they could choose that security setting as well. What do you think?
