Social media is in its so-called unhinged era, where social media managers are breaking the digital fourth wall and speaking the language of the internet from branded accounts. At the helm of the unhinged social media movement is a big green owl, Duo, brand mascot for the language learning app Duolingo.

Duo has made a name for itself on TikTok with funny skits as the social media team behind the owl works to humanize the brand. But sometimes, like Icarus, Duo sometimes found itself flying too close to the sun. Last year, the brand came under fire for a comment on a TikTok about Johnny Depp and Amber Heard’s defamation trial.

It’s been a lesson in toeing the line, learning what works and what doesn’t. Experimentation may be the cornerstone of Duolingo’s social media strategy, but Duo’s unhinged personality is here to stay for now with the company planning to explore other character personalities from the Duolingo universe in the future, said Katherine Chan, head of global social and influencer strategy at Duolingo.

“We have a running rule that we have no rules,” Chan said on the most recent episode of the Digiday Podcast. “We basically have a set of guardrails in terms of absolute no's for the brand. But outside of that, there’s a lot of freedom and empowerment to try to draw the shortest line from ideation to post.”
