Yes completely. Zcash Media will once again fail to make a broad impact if they aren’t doing the 101 level work in the lead up. @David_Heisenberg gave some helpful updates, but made no remark about how the Zcash Media accounts will be warmed up in advance (or how the community can help do some of the warm-up efforts) to the start of releases in October.
YouTube shorts are the best engagement drivers on that platform today, Zcash Media would be shooting itself in the foot by not getting active with that format asap. (If nothing else, there ought to be a series of recycled clips from the first 2 major video releases as shorts). This is 101 level stuff, its a bit discouraging that their Zcash Media 2023 proposal was accepted despite having no specific plan for how to keep their existing accounts active and engaging.
Your point about the other Zcash YouTube accounts is also good, they could be clipping and releasing shorts also for their respective audiences… Zcash Brazil and ZecHub come to my mind first.
