The principle is fine, but the name "bit" isnt going to help acceptance, it has too much meaning already, in common language (i'll have a bit of cake), technical IT especially networks and colloquially. Need to come up with a better name (shame Satoshi already seems defined)
It's good enough. Language is fuzzy anyway.
It is not "good enough", its outright counter productive, having slept on it i find i like the idea even less. English language is fuzzy because of the natural evolution of it as people accept a meaning change and morph to it, usually attempts to generate a word or force a new meaning fail. This could end up making acceptance more difficult as it will cause confusion, people will rolleyes and walk away.
