Hi Noah,

thanks for this update, it is very interesting.

I find this foray into "URIs are cooler when humans can actually  
fiddle with them (at their own risk)" to be highly encouraging. I  
think however that it is incomplete without an adjacent discussion of  
when and why it may (or may not) be appropriate to take active steps  
in preventing users from being able to "explore and experiment" with  
URIs, notably through such devices as including the creation year in  
the URI (aka datedspace).

I wonder if a discussion of metadata in URIs that are not necessarily  
dereferenceable (e.g. namespaces) could be useful. One aspect of this  
is including the version number of the vocabulary in the URI. Another  
is related to the above "hackability" of URIs but in a lesser form,  
that is how hard should it be to remember a namespace URI, notably in  
the context of an organisation that produces a great many of them,  
and which authors will need to manipulate on a daily basis.
