The way I see it, editing is a very “buddhist” activity – you’ve got to make your own ego very transparent and serve the author’s voice, not show off with your own skill. I think a good editor should be invisible, or at least make themselves as transparent as possible. You know something’s happened to the text but you can’t exactly pinpoint what. Sometimes I even have to look for what exactly it was I did to a text when a customer tells me I made it so much better. It’s very much in the details. But I guess that’s a personal thing – I think I’ve got a “minimalist” editing style, I will never bulldozer through a text.
