Content half-life
|

These new realities:
- Long tail: NAP 2006, 15000 items possible, 1100 bought once, 3600 < 10
- The publishing tradition of 3-year lifespan for a book: no longer true; no meaningful content need ever die
- Our markets are now so wide but so shallow that we cannot find them: they will need to find us,
Drive these realities:
- Any content that can be reused, reread, repurposed, or with historical value,
is worth richly digitizing (via XML or other structured text), and/or richly enhancing with metadata.
- Almost any "dynamic" information (news, stocks, AMPCI data) requires "born digital" to be salable.
