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. Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. ZDNET RECOMMENDS The best encrypted messaging apps
