no-www is a movement to deprecate use of "www." at the start of URLs as being redundant, unnecessary, and a waste of resources.

www prefix is a source of bugs

  • 2023-11-10 Webmentions Working (W)once Again

    I fixed the issue I was having with the WordPress Webmention plugin. I had a hunch that it was being caused by the plugin trying to send webmentions from a url with the www prefix. Once I changed my site url in my settings to not include it, they started sending again.

    Emphasis added.

some browsers hide www prefix

  • Another reason to setup www. to permanently redirect to your plain domain: apparently (some) browsers hide the www. in the URL bar and when users copy/paste it doesnโ€™t show. Thread:
