> I think that one should at least have one's own domain instead of example.substack.com.
I thought about this question when I recently started writing a few articles on Substack.
I chose not to use my own domain, even though I have a few.
Why? I want my writing to outlive me.
When I am no longer able to pay for domain renewals, my own domains will expire. Hopefully {my-hn-username}.substack.com will still be around.
Time will tell.
>{my-hn-username}.substack.com will still be around
I wouldn't be so sure. Platforms come and go, they change domains (e.g. Twitter), they merge, they die.

It's very unlikely Substack will still be around when you die, if you're younger than 60.
This strategy for your legacy would not have been successful with stratoscope.geocities.com (RIP 2009), skyblog.com/stratoscobe (died in 2023 with no data export path offered), Posterous, MSN Spaces, Vine, and many others.
I am willing to bet that most of my domains will outlive "username.substack.com".
