The Rise (and Decline?) of Websites

Jakob makes an important observation in his latest alertbox on search engines as answer engines (original emphasis):

"Websites" weren't really a tangible concept until 1993 anyway. The pre-Mosaic Web in 1991 and 1992 was exactly that: a web of information where the fundamental unit was the article, not the server hosting a particular webpage. This new user behavior is therefore a reversion to the Web's original vision to some extent, though not completely because users still have some favorite sites that they treat as resources in their own right.

I'm certainly biased, but it seems that another shift is happening toward the post (<item> or <entry> depending on your preference) being the fundamental unit. As dedicated content applications (like feed readers) gain marketshare, and cool features like feed splicing are made available, it's easy to see a decline in the usefulness of the all-purpose visual browser and, thusly, websites.
