A reply-first routine that builds a small audience over months, not days.
With no audience, posting is shouting into a void. Replies are the only mechanism that works from zero, and the timescale is months.
Thoughtful replies to mid-sized accounts in your niche. This is what puts your name in front of the audience you want.
Those get shared. Announcements and milestones do not, unless the number is unusual.
What it is, the problem, one demo clip, what you learned building it, the link last. One thread, not a series.
Three to six months before this channel does anything measurable. Plan it as background work alongside the rest of the route.
