Robin Sloan drops some smart science:
Also: what’s a media inventor, anyway? Here’s my (totally made-up) definition: It’s somebody primarily interested in content who also experiments with new technology, new processes, and new formats. Allen Lane was a media inventor. Early bloggers were media inventors. Right now, the indie video game scene is full of media inventors.
Fundamentally, I think, a media inventor is someone who isn’t satisfied with the suite of formats that have been handed down to him by his culture (and economy). Novel, novella, short story; album, EP, single; RPG, RTS, FPS — a media inventor doesn’t like those choices. It turns out a media inventor feels compelled to make the content and the container.
