Social networks are changing how we get the news. Just sign on to Facebook or Twitter, and your friends will point the way to the most interesting, viral, or newsworthy content on the web.

Yet, for many people, the sheer volume of it is getting to be too much. If you follow the kinds of people who tweet frequently about the news, you’re lucky if you’ll see beyond the last 10 minutes in your tweet stream. The Facebook news feed is great for telling you what your friends are saying, but there hasn’t been a great way to data to see what all of Facebook is saying.

It’s this latter problem that we are keen to solve.

Facebook is by far the biggest social platform on the Web, with over 550 million users, making it several times bigger than Twitter in size and influence. Since they released the “Like” button for articles on websites, it has proven to be a very useful tool for website owners to promote their content within Facebook and showcase the most popular articles on their sites.

Finding the most “liked” articles across the whole Web is a different story.

Unlike Twitter, it’s difficult to mine the most popular links on Facebook because a very small percentage of users leave what they post open to those who aren’t friends with them. If you see that 1,503 people have “liked” an article you’re reading on NYTimes.com, it’s nigh impossible to figure out who those people are — how many people “liked” it when it was posted to the Times’ Facebook page versus those who posted it to their own profile, and the people who liked it from there. And wouldn’t it be great if Facebook had a page summing up the most “liked” links on all of Facebook in the last day, week, or all time?

Knowing these existing shortcomings, we sought to build something that would aggregate the most relevant and liked articles from the most popular news websites on the Internet in a single place.

Today, we’re introducing Newsbook, a cheat sheet for the web’s most important news, curated by Facebook. For the sites we’ve seen generate the most “liking” activity, it shows the most shared articles from those sites on Facebook. If you’re logged into Facebook, you can see what your friends are recommending. To enhance discovery, we’ve also expanded the number of stories visible beyond what a typical news website would. You can easily navigate between different types of sites from politics to technology to “big think.”

I often find that the biggest test of whether a product will be useful is if I find myself relying on it before it’s even released. That’s already been our experience with Newsbook. As a news junkie, it’s one of the first things I check in the morning. We hope it will be for you too, and invite you to check it out.
