Originally Snapchat users were only identifiable by user names but in 2016 Bitmoji’s were implemented. Bitmoji’s are designable avatars that reflect you. You have the ability to choose everything from the outfit it wears to the beauty marks for the face. With Bitmojis being implimented it allows you to put a human-esk face and humanize the social media more. Before there was a disconnect with just sending things but this potentially makes people think twice about what they are sending. previous to this installment Snapchat was used for sending nudes due to the image “disappearing” after a set period of time but that is on the decline with the bitmoji update. coincidence, maybe.
