The term bounce has a well defined meaning. People going away from your page, without reading it.

And it's not the parent that holds to that meaning, while I (and the article) distort it to mean something else.

It's Google Analytics that doesn't really measure bounce as people mean it. They measure not visiting a second page a bounce (!).

This is not the proper way -- and is probably used due to limitations in tracking ability for exiting a page. And while this might work for a site with a landing page -- where the content people look for will somewhere in another page, it doesn't work for a blog like site. If somebody reads my blogs main article for 10 minutes, that's not a bounce by any stretch of the word.

So what the author does is propose a way to fix GA to properly measure bounce rate the way men and god meant it.

He doesn't propose some alternative meaning for bounce rate.

If anything, that (using an alternative and not true meaning) is what GA does. GA redefines "bounce rate" by showing something which is not the bounce rate.
