I often feel that 'we' is a better substitute than 'you' anyway, assuming a desire not to personalise. People seem frequently to say ridiculous things such as "you don't - I mean general-you, not you-you - ...", why do we (<-) go to such lengths to avoid the perfectly fine and much more succinct 'one'?

'We' has similar problems, but at least even if taken specifically and personally it includes oneself; thereby it's less likely to be taken as specific criticism or personal insult, etc.
