Let's say that I defined a new term in my writing, such as (yes, it's second-person):
You spot a Holo-Reader—a long, silver metal tube that records holograms in three dimensions for later playback.
It's pretty clear that the first time I mention and define the new term, it's a name, and thus should be properly capitalized (as "Holo-Reader.")
But what about subsequent uses of the term? Should I capitalize it or not?
I feel personally that maybe I should, but it draws too much attention to it and treats it as a name; whereas now, it has become part of the lingua franca of the reader, of the world in which the writing inhibits; and is therefore not a name, but a "common" object.
How should I deal with this in my writing?
