The News Brief revision will most likely involve re-ordering the information in there and highlighting the most interesting "newsy" things in it, as well as tweaking the wording to be more precise and/or interesting.
The Profile revision should be interesting, because after writing my initial draft and receiving feedback from my peers I re-wrote the entire thing. But even after that, it's not that great. I struggled writing it because I didn't feel I had the authority to write such a thing after a half-hour conversation in which I probably asked the wrong questions and looked like an idiot, so basically I'm lacking confidence in it. That's why I think my "editor hat" will be especially helpful when I revise it, because I can work with what's there and more objectively decide what's missing or how to best present the stuff I do know.
