this website is running a bespoke platform which has a trilogy of facets:

IdP

it acts as an identity provider; this is nerdy technology

WWW

it acts as a web site, serving up html pages of wisdom (like this very page you are reding now).

it suppoorts blogging, so you can read the parts of my journal that are public.

Social

it acts as an ActivityPub server for participation in that nebulous thing called the fediverse.
