I can never resist using "death" in a blog title-- I can't help myself. Jeremiah Owyang could have worked death into this title: URLs will be an Anachronism:
After playing with Google’s Chrome browser for the last few days, I noticed the “Address” bar, which is just called a “Omnibox” (corrected from just “box” via comments) is really a search field. Anything entered into it will deliver a webpage (it first looks at your historical activities) or renders Google search results (or search of your preference, including twitter search). As a result, it’s become apparently that I no longer need to enter in URLs to my browser for 99% of all tasks.
I've been saying this for sometime now, most recently two months ago: Do domain names even matter anymore? That Google has now codified this is further evidence that the Web site as a concept is history.
