Back to the Tweet that sparked this thread ...
Not sure which would pish me off more as an editor, having the beat writer taking a phone pic, getting in the killer cover shot of the post-game celebration, or her bringing attention to her being in the killer cover shot the next day on Twitter.
No problem with the first thing for sure -- with social media the way it is, it helps add to the coverage with a more up close perspective. The 2nd I don't think can be helped / was intentional. It's going to happen in situations like that. Now the third point, I don't think I'd bring that up.
