Here is Bob Baldwin, an engineer of Facebook, post regrading that Facebook update last October 14, 2014:
New on Facebook: You can now send stickers in comments!
Stickers have been a delightful way to communicate in messages, and I'm happy to announce we're bringing them to comments across Facebook. Just tap the smiley face icon in the bottom-right of any comment field to pick a sticker to send. It'll be available to all posts from people, in groups, and on events now. I think stickers will allow people to reply to a variety of posts in a more fun way than words alone. You can now easily show your excitement for a post with good news, cheer up a friend who's feeling down, and express a variety of more nuanced reactions.
Stickers in Comments was started as a hackathon project in New York with me and Kwame, where we built the prototype for web in a single night. When we turned it on for employees soon after, they loved it. We later built it for mobile web at a hackathon in California, and the iOS & Android versions soon after. Thanks to everyone who helped build this, including Kwame Thomison, Yu Chen, Mike Rumble, Anthony Chan, Michael McDuffee, Vihang Mehta, Mark Peng, Joshua Clark, and others. Special thanks to Chris Cox, Chuanxin Hu, and Sammi Krug supporting this project.
Comments has been one of my favorite parts of Facebook to hack on. This was my third hackathon project to add richer content to comments: first was emoji (May 2013), then photos (June 2013), and now stickers. Stickers in comments will rollout worldwide over the next day or so. Enjoy!
