For me, it's worth it, but only because it's really low effort.

I don't "write" for an audience, it's just about non-controversial technical topics that I write for myself. If it's already in an org-mode format, why wouldn't I publish it then?

Some people find it useful, I also find it useful when I need to refer to my notes in the future, to know where to look at.

That being said, I never had an intention to have a big audience, or expect any business related gain.
