Signal is moderation.
Generating signal is moderating noise. The first moderator of any message is the person converting ideas into language. Understanding the interplay of how messages get moderated by the various layers they pass through is what media literacy is.
I miss when signal-to-noise ratio was common parlance of the Internet.
Making usable spaces is tough work, but having worthwhile content drowned in an ocean of noise is seemingly the default of corporate controlled media anymore, so much have they abandoned paying attention to what they publish. That you don't know who is editorializing and moderating the places you frequent and have opinions on the job they're doing says to me that you're not doing the work that being media literate requires, which is all the more important when so much of it is generated content with no consideration given to reality.
