Hu.Man is a mysterious figure who does not talk much on the Repl.it Discord. He (She? They? It?) joined the Repl.it team as a platform team intern in early 2021 and talk until approached in a group chat outside the server. They are a big fan of Python and Go. They are also in the PDT timezone. Though they don't talk much they admit to lurking.
It is highly likely Hu.Man is actually Winnie the Pooh, a fugitive who is fleeing the Chinese authorities, based on their pfp. The username further contributes to this theory as Hu.Man is 'human' with a period inside. Winnie the Pooh is a non-human, so it would make sense for Winnie to disguise and claim to be a human.
His name appears to be Newman Hu, from a post he authored on the Replit Blog with a few other people.
