Mashable reports on Facebook’s Year in Review for your friends.

On top of the Year in Review feature that highlights your top 30 moments, Facebook has introduced the Year in Review for your friends.

Facebook uses a different algorithm than the one that surfaces News Feed content. The Year in Review is made up exclusively of “life events and popular posts,” according to a spokesperson. The “popular posts” are determined based on engagement like comments and Likes.

Another new feature that will soon become a Facebook tradition.
