Perhaps the most shared information in this day and age is news. With the rise of social networking and mass dissemination of knowledge, it is astounding that no service exists purely for the purpose of sharing this information. While some companies aggregate news that your followers are sharing with high frequency, no service exists that emphasizes following people because of the news they share.
The most important thing to a functioning society are ideas. Without expanding your horizons, you will never recieve new ideas or experience different perspectives on global issues. I aim to create a service that does exactly this. People will follow "journalists" based upon the type of news they share and the commentary that they provide on these issues. This will topple the system of information being only propagated by large news conglomerates, and will instead allow individuals to create and share their own opinions on current events. Their network of followers will then share this information for all to see.
In essence, this is a social news aggregator. You don't simply get your news from the sources you've known your entire life, and you don't get it from the people you already know the viewpoints of. By choosing to follow individuals based upon the news they create and share, you turn the current system up-side-down.
