 I'm old enough to have grown up in an age where personal websites were common, though many were hosted through sites like the long-gone [GeoCities](https://en.wikipedia.org/wiki/GeoCities) and [AngelFire](https://en.wikipedia.org/wiki/Angelfire). The web was a lot of little sites where people shared their passion or just a little bit about themselves. Search engines used to be one of the major tools for finding these sites, along with directories and [web rings](https://en.wikipedia.org/wiki/Webring). I spent many a teenage year browsing around sites looking for more information on Magic: the Gathering, Dungeons & Dragons, or learning how to build my own sites and wrangle with that new-fangled CSS thing.
 
+## What is the Indie Web
+
+The Indie Web seems to have come out of Bruce Sterling's IndieWeb Camp way back in 2013. There he outlined a few major principles, which are [largely unchanged today](https://indieweb.org/principles).
+
+I think it can largely be summed up by two major themes:
+
+- Build things for people. You are the first customer so design for yourself and what you love. Don't agonize about making things interoperable for machines.
+- Build things that last. You should have control over the data and site. It should only loosely depend on APIs and platform
+
 So how do we go about joining the Indie Web?
