The main idea behind this Web App is to provide a personalized version of FB.With this idea, users will be able to customize the entire App just the way they would want. The four main features would be:
1- A search engine which would be more advanced than the current FB search engine. An extremely human readable search query.
2- Sharing stuff here would only be accessible to the people you want to share with. It will provide a more personal feel and better communication features. Such as an option to send a Voice Message when your friend/family member post something.
3- A bookmark button. Can be used as a reminder for the things you would like to do in future.
4- A travel folder which will only show posts from the people who are traveling.
