revolutionary changes
Editing involves so many arbitrary changes to suit style (serial comma), to avoid baiting someone else’s bête noire (‘since’ only allowed as a temporal adverb), or to satisfy the conventions of genre and jargon (‘discriminating power’). My latest arbitrary textual reaction is to ‘revolves around’, as in ‘the conversation revolved around the sound of chymes’ (to be nonsensical about it); it seems to me that unless some sort of circular motion (physical or logical) is involved, that this locution should be avoided as being at best imprecise and at worst (well, to me) inelegant. In short, for the moment, I dislike it – but perhaps I’ll come around.
