Of course. Though they aren't the only think considered. They are  
considered along with other human-comprehensible location data (ie,

I think these problems are already somewhat solved with hcard/vcard.

No need to reinvent hcard here.

The location data discussion has been pretty quite as of late, but  
the working hypothesis we came up with is

1. Extract the adr construct of hcard to use for recording locations  
expressed in terms of human readable addresses
2. Extract the geo property of hcard to express lat/long.

I tried finding where I made these statements in the archives, but I  
can't seem to find them.
