Obviously, the name "Metacite" infers something about metadata, which is sort of a pet subject of mine. I want Metacite to store and generate rich metadata and make it available to publication managers in a structured way, allowing for interesting applications (even though I can't think of any yet). For now all I'm planning to do with the facility is add a didactic element to my magazine by allowing readers to peruse the creative and technical process behind every image, block of text, animation and so forth. Fully fleshed out this could lead to web resources I used for production purposes, discussions of technique, essays I've written... really tie the magazine into the rest of my site as a whole.
I'm sure there are more worthwhile uses for this, though, so I'm excited to see what emerges when Metacite goes public.
Short update tonight. I've got to get back to the code, as well as come up with an itinerary for hanging out with frizzlefry tomorrow - and get to bed early.
