The New York Observer has a question: What is platform-agnostic?
The term is applied in a variety of ways by media organizations. In some cases it means that the newsroom publishes across platforms with no particular preference for one over the others. In some cases it means publishing discrete content for one platform that doesn't necessarily take an audience away from the others. In other cases it means the content runs equally well across any platform.
Our use of it, at least for the time being, appears to involve the first two of the three. Like most newspapers, we have taken to breaking all of our news online (which is actually a Web-first, not platform-agnostic behaviour). And we will carry different accounts of stories across different platforms when it merits (some breaking-news dispatches won't wear well by the time the paper appears, and most such dispatches need to be written with greater urgency than would be wise for the more reflective print edition).
It may take time for the third meaning to surface. If writing practices change, or if e-ink editions emerge for newspapering, then we'll likely see content work across platforms equally well. For the time being, though, there is repurposing or reworking of information for different platforms.
