Feel free to revert any copyediting I do. If I support on prose during an article review: I'm only checking the text, not images, infoboxes, end sections, links, or hidden codes. If I oppose: publishers are more interested in good writers than in writers with good copyediting skills, so if you enjoy writing, keep at it no matter what the copyeditors say.
Effective April 2015, I'm doing more FAC copyediting than I used to, in part to get up to speed in the issues that come up in my new job. If I support the nomination and list a few potential problems, it's up to the reviewers and FAC coords to decide whether the problems are a big deal or not. Usually, I won't have time to keep up with developments after I support. I'm looking only for things regarded as mistakes at FAC, not matters of taste.
