different answers. A better question might be, "How do you name things
(e.g. people)". If different parties name things in a similar way there's
an order of magnitude more chance of growing the network. Keybase has a
proprietary, centralized naming strategy largely incompatible with the
architecture of the web. If that sounds like a criticism, it isnt.
Because almost everyone else does the same thing. Hence identity systems
Where I think keybase shines is with convenience and utility. Such systems
have chances of organic growth. But people tend to over estimate the
chances of making it to millions of users, which is what keybase possibly
needs to change the landscape.
We need a web of trust that's universal (the only way I know to do this is
to use URIs for naming), so that it can span many systems and grow the

In awww this is a document, we like to put data inside documents. Then you
can make statements about both things. I may like Ricky Martin's home page
but may not like Ricky Martin.
Id suggest having an anchor inside such as #me or #this, then tie key value
pairs to it. It turns out that anchors are very hard to grok on the web
for most people, though.
Using anchors also allows multiple data structures on the page. One for
the user, one for the key, one for anything else you'd like to add.

yes, but as it's designed hard to get traction
very worth while noting the usability patterns tho
