Human relationships offline are not equal. There are mutual friends whom users are comfortable sharing their mobile numbers or profiles with, and then there are complete strangers. Kakao provides a middle level of interaction with this new feature. Open Chat connects users through links; as opposed to regular chats, which require the exchange of phone numbers. Open Chat allows users to have more control over their friends list and gives them a secure alternative: to chat with whomever they need without having to divulge personal information.
