objection

For two reasons:
1. Using the adress bar as a search bar has become interesting browser 
input standard (wich also could lead to interesting new ways to actually 
browse)
2. I think these potential super-top-level domains would be better 
served as localised domains, defineable by the local isp
think of http://911 or http://emergency....providing a list to local 
help services..etc.
Just a thought
