Developing social channels based on exchanging a single message isn’t exactly new, of course. Back in 2014, the “Yo” app was launched with the sole purpose of enabling users to send each other the greeting “Yo.” So far, more than a dozen different members have contributed to the group, posting voice notes of themselves screaming, yelling, groaning, and wailing in various pitches and rhythms. Public channels are public to the internet, regardless of whether or not they are subscribed. A public channel is displayed in search results and has a short address (link). End-to-end encryption is an important feature in messaging, as it's the first step in protecting users from surveillance. The Channel name and bio must be no more than 255 characters long
