Curious your opinion on newsletter trends: is there still a demand for content branded as "publications" a la Substack? Will the personal brand ever come back in style?

For example: I can never remember the name of Parker Molloy's newsletter The Present Age but I read it every day. I don't think about it as reading The Present Age, I think of it as reading what Parker has to say today.

But what do readers/customers/consumers want: more branded publication channels or named creators with personal brands?
