Hm, maybe I need to give a little guidance. Sorry. I don't search for a real name or the correct word. I need creative input or synonyms that come from "outside the box" i.e. that I don't find in the synonym dictionary. (thanks for reading anyway, kaoskat.)
The one who reports from a festival could be a reporter, a gossiper, a storyteller, an informant or anything you can think of.
The mix of the news could be: festival news, input or something like that. (this one is tough)
The process could be described as tracking, hunting, searching etc.
