20 Conflicting questions on creating disposables

I think it's time we called consumer culture what it really is: disposable culture. In a world that's all about disposables, and the value of things lying in their obsolescence, what lasts?

More pertinently, how do we make content last?* How does content retain its value? Conventional wisdom implicates:

• Evergreen content: re-churnable, "timeless" content.
• Print: let's face it, a book you read six months ago is almost always easier to find than some article you read online on the same day.
• Epublishing: in theory, although my computer's directory structure appears to be some kind of vortex that sucks such content in and destroys it through what I suspect is a previously undiscovered form of massive, sub-atomic implosion.
• Searchability: will social search put paid to the conventional notion of "value", or bolster it? And what about supposedly less-restricted search, like Duck Duck Go?

But really, what is the value of content? For most people, it seems to be that you can stick it in your head -- you can gain knowledge (even only short-term knowledge, like news), or a semblance of such.

What are the alternatives to disposable content? Are there alternatives? If a central part of the human psyche believes that the most valuable things are those we can lose, and/or that what matters is what's "now", then perhaps obsolescence is to be reveled in.

Perhaps the value of content -- to people who sell it, and people who read it -- is proportional to its ability to churn.

Why am I arguing? Obsolescence will keep writers in jobs, and by rights I should probably be cheering. There'll always be more to write, and more to read. But Jesus, it's exhausting.

*Substitute for "content" the name of the product you make if you wish.
