***FS***Sahar brings up the comparison of domain names to real estate.  These comparisons will never go away, and for good reason, since they are comparable, though they aren’t the same. Ultimately what we’re “overlooking” today is the thing we don’t see coming..  a split platform of navigation where future browser manufacturers and search engines bring back the “realnames” concept to run in tandem with existing URL’s ..  looking for Hoover Vacuums?  Just type Hooverin your future iGoogle Browser and directed to the most popular front door. There will always be a domain name to match because you need a domain for email and not everyone will navigate using the same standardized browser..  but there will be a gradual marginalization of navigation toward other conduits such as search engines and browsers.
