I started a newsletter on Substack in June this year. I will send out my 100th post tomorrow morning!
I still write on Medium, but not as frequently lately. I have tended to write fairly long stories in the past. They take a lot more effort, research, and editing than my newsletter, which is more informal.
I’ve also been monetizing my newsletter, and it’s doing ok. I have a feeling that I’ll reach a tipping point in 2020 when it will be more rewarding to focus my efforts there.
