Here are my thoughts on some round numbers, particularly with respect to the sustainability of Rhythm Changes and where it could take both you (the customer of RC) and me.
100 subscribers
You: RC is mostly the gig list and email to deliver it, plus some social posts as well as the Rhythm Changes Podcast. The coverage is a nice touch but incidental.
Me: RC is fine to keep doing, as long as I enjoy spending time on it. I think often about my editorial budget and which events to attend.
200 subscribers
You: A new delivery of some regular, useful subscriber-only service appears on top of or alongside the gig list, but it continues to gather people almost exclusively in Metro Vancouver.
Me: RC is a promising part of my work. I attend events more liberally, further differentiating my coverage.
300 subscribers
You: The delivery of in-person experiences strengthens the Metro Vancouver subscribers' ties to each other.
Me: RC is a viable, healthy part of my business. My lifestyle and career is sustainable with this amount of RC earnings plus the client work I do. This milestone is arguably the most important one to target.
500 subscribers
You: The coverage and the event planning begin to face other Canadian cities, drawing subscribers from beyond Metro Vancouver for the first time.
Me: I begin to taper my client work so that RC is about half of my work time.
800 subscribers
You: RC faces the entire Canadian jazz scene, which brings people from different cities closer to each other.
Me: I work full-time on RC.
1,000 subscribers
You: RC has distinct chapters that each have local contributors plus regular events in Canada's largest scenes.
Me: In theory, I no longer need to live in Metro Vancouver to operate RC.
