Mrs D wrote a fantastic poem about the IndieWeb:

A static site maker, for a place to begin.
A layout with markup (or just add it in!).
Host it on GitHub in public, for free
or fill up a bucket for a small monthly fee.
Webmention.io to make replies go,
Bridgy to POSSE to your old silo.
Mix with community for sugar and spice,
and enjoy owning your web paradise!

And there’s a nice article about the IndieWeb as well!
