I’m trying to understand who the target audience is.

Phrasing my comment a slightly different way: what’s the point of writing *in public* if you don’t get feedback?

For me

- Writing publicly is minimum viable pressure to make me better formulate my ideas. It doesn’t require feedback; 80% of the value is in my words being public. When my ideas are better formulated, it leads to me new ideas I wouldn’t have had otherwise

- Over time (I’ve been blogging since 2000) I’ve found that the most valuable feedback is in email. You don’t get good signal to noise in comments or Web Mentions. RSS + a public email address is all I need

- I can afford for my network to grow slowly. I don’t need to build big community with flurries of debate in a comments section. Writing publicly is an excellent way to keep in touch with the broad network I already have

You are misrepresenting it: Not caring about numbers/analytics isn't "no feedback". People can still leave comments, email, ...

And the usefulness of writing isn't connected to if people can reach the author or not.

Too much feedback (especially when it comes to sharing your own thoughts) poisons the purity.

It’s a cliche that every musicians best work is their early stuff. Once you become popular, famous, entangled in expectations and opinions, you lose the thing that made you great.
