[Air-L] quick research question re social media news feeds

Dear all - I have a vague memory of seeing some work that had been done on whether/how the news feed shapes/flattens communicative and/or epistemological hierarchies. E.g., updates from news sources of record are mixed in with other updates and there is less of the contextual information that would distinguish one set of updates as being more factual, more authoritative, etc. I can't remember much else about this, but if this rings any bells, I'd very much appreciate a pointer in the right direction.
