Randy Skaggs started Q108 Kingston as a Friday night hobby, hosting a small online radio show for his work colleagues. Five years on it plays hard rock, melodic rock, and glam metal around the clock to listeners across Ontario, with several weekly shows Randy hosts himself. He runs all the promotion alone, which means the person on air is also the person who should be posting. Those two jobs cannot happen at the same time, so he stopped trying to do both.
His fix was to write the tweets before the show started. Every 15 minutes during a broadcast, a post goes out naming the song playing and telling people where to tune in, five or six times across the show, all queued in advance. He is on the mic, not the timeline. The replies are what make it worth doing: artists thank him for playing their track, and listeners write in to say they tuned in or to thank him for a request. He builds his Friday Special posters in PosterMyWall, picking fonts and props that match the era he is playing.
You can work the same way for anything that happens live. Build the graphics from X post templates, let AI Writer draft the captions in one sitting, and queue the lot with the X post scheduler before you go on. Lay the week out in the Content Planner so a show, a match, a sale, or a set all have their posts written days early. You turn up for the thing itself and reply to people, instead of writing copy with one hand.
