I see some good, positive comments in this thread.
Some additional thoughts from me. If (big if) we intend this to be worldwide, I think we need to find a good, universal term for rubbish.
What applies in Australia may be almost unheard of in the US or UK. That's one of the things I find annoying about CITO. The word trash and the rhyme with cache.
Here are some synonyms for what I think we're looking at:
Debris, detritus, dreck, dregs, droppings, dross, excess, filth, fragments, junk, leavings, litter, muck, oddments, odds and ends, offal, pieces, refuse, residue, rubbish, rubble, rummage, scourings, scrap, scraps, scum, sediment, sewage, slop, shavings, sweepings, swill, trash, waste.
Obviously they can't all be used. I don't think I want to clean up sewage.
So what catchy names / acronyms could we come up with? I know with all of the cool cache names out there, there has to be someone(s) who can put their nose to the trash can
