> 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.
