I think your post should be 'personal data', not 'big data', but that doesn't answer your question. But maybe I'm not understanding what you mean about your 'hard work'. I think you're talking about your personal information, but maybe I'm confused. You could store your personal data locally, but would you back it up? Would it always be accessible when you need it? What about when other people need it, like your photo in a feed. So local storage won't work. You could store it on your own personal cloud, but is it really personal? Somebody needs to run that service for you. That means somebody has access to your data, and every other service would need to be able to connect to that service. That is essentially what Facebook,iCloud,SkyDrive,etc. provide. Facebook just happens to have a front-end that you can interact with directly as an entertainment service and they can sell advertising based on you accessing your and your friends information.
