I'm with Halo. I know that during a go-around everyone's very busy and having a calming chat to the pax isn't high on the checklist, but it would do a great deal of good to let people know what happened at some point before they get off. Doesn't have to be a full debrief, just "I know some of you will be wondering what happened just then, it was a normal routine to ensure good safety margins on landing. We didn't land first time around because the a/c in front of us was a little late departing the runway, and in such circumstances it is standard procedure to go around and give everyone more time." Or whatever. If you're not comfortable doing PAs (I've heard a few mumbled announcements that really should have started "Unaccustomed as I am to public speaking..."), practice something along those lines when you've got a spare few minutes so you'll be ready when it happens next. It WILL be appreciated.
Lots of passengers are very nervous about flying, and it's not just those who only fly once in a blue moon or look as if they expect the worst. It's very noticeable how quickly the atmosphere down the back gets tense as soon as things start to depart noticeably from expected -- and you may not think it's right, but a couple of hundred people who really thought their next in-flight briefing's going to come from the Archangel Gabriel is worth a story.
I'm not defending shoddy journalism -- which annoys me far more than it annoys you, trust me! It's no fun being in a business which attracts such opprobrium -- but everyone has a role to play in making it harder for the sensationalists to get away with it. You have a captive audience who want to know what happened: get to them before the Klingons do. Who knows -- there may even be an editor back there who'll spike the next bit of non-event nonsense that passes their desk as a result.
