2017 was a jam-packed year for all of us. Here at Reddit HQ, our teams have been hard at work to ship more product than ever before—from native video to major upgrades to our mobile apps. Meanwhile, redditors have been hard at work creating more content, conversations, and communities than ever before—with 230,000+ Reddit Gifts sign-ups, 7,000,000+ Reddit Live thread updates, 900,000,000+ comments, and 12,000,000,000+ upvotes, all in the past year!

Sure, the year’s not quite over yet, but we wanted to take a moment to share some highlights from 2017 (and a few of our communities’ own “best of 2017” posts).
