View source for The distributed dns system I want

Let's say I have a friend named fred. Then I want to be able to see their blog like so:

 fred.net

Realistically though there's a lot of freds. so maybe the way I get to their site is more like

 fred183.net

or

 friendlyfred.website

However it's not necessarily realistic for every friend to have their own subdomain:
* it costs money
* it takes technical knowledge and time
* it shuts down if it is not maintained, either due to bit rot or missed payment

So then web 2.0 comes along and we have platsforms that allow people to host their content:

 fred183.blogspot.com
 twitter.com/fred183 (or simply @fred183)
 facebook.com/fred-rierden-10183

And this works pretty well, but then we're always behonden to the platform to be able to post. If they have a glitch / downtime / etc the content goes offline.

So web3 has some ideas of how to make an id like

 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2

and have that be the point of reference; it can be turned into a qr code, or maybe something like 

 razzzzi*keybase.io

which looks a lot like an email...
