From the article:

> Because sites on my.WordPress.net are private by default and not accessible from the public internet, they don’t behave like traditional websites. They aren’t optimized for traffic, discovery, or presentation, and they don’t need to be. Instead, WordPress becomes a personal environment where ideas can exist before they are ready to be shared, or where they may never be shared at all.

One of the main ideas of the internet, and therefore WordPress, is to be able to share stuff on the public internet.

Without that capability, I wonder who would this be targeted towards. For personal note taking there are numerous software already out there.

This [1] used to be the place but it got less maintained as time went on.

I see this as an example of being able to build complex apps in a browser, which are much more portable than system apps.
