The same goes for Messenger, which opened its platform to third-party apps on Wednesday to give people options like GIFs and memes without adding a whole mess of features.
"We could've built a lot of those capabilities in Messenger and made it slower and less reliable, and we didn't want that," Marcus said. "We want messaging to be super fast, reliable and dependable, but at the same time want people to have those creative tools.
