This has been a long standing concern of mine as well. I even see new articles telling people how easy it is to set up IndieAuth where they only set up RelMeAuth and don’t even declare indieauth.com as an endpoint! That won’t work for the vast majority of IndieWeb services, and what’s more these articles still talk about using Twitter for it even though Twitter hasn’t worked for RelMeAuth in years.

So not only are they confused by indieauth.com, they’re not even following its setup instructions.
