A coin with only one side isn't a coin. A one sided coin is a coin with nothing on one side.
Nothing means little.
The web could not exist if we couldn't keep anything, so, even though the trend has been towards not keeping anything, certain halfhearted efforts have always been made towards allowing us to keep things. Now that the trend has reversed, so, after the flip, the trend is towards keeping everything. Oh Glory!
Not keeping something means destroying it. Keeping it means putting it someplace. Someplace is not just any place. Just any place is a form of destruction. This is why the trend has been towards not keeping anything. Creating places that are not any place is an art. Here at the time of the flip, we are still learning that art, and are uncertain as to how it operates. In fact, that is the nature of art. It is a form of doing the impossible, or maybe that's just what it is, doing the impossible. This will not prevent us from doing it. The trend has nothing to do with the problem of volume.
By the way, to do the impossible it is necessary to do something other than the impossible thing, so, you create a tool. Artists make their own tools. We are in the tool making business.
The current web trend began in the 18th Century, with the emergence of the pamphlet. This was something designed to be thrown away. It grew into the newspaper and the magazine, 100 pamphlets in a single volume. Now it is the web, 100 million pamphlets in a single volume. Having reached this culmination, it flips, and the time has come for keeping again.
