Aside: Has anyone analyzed social media in terms of it's inputs and outputs and distinguished what factors are most critical/useful to achieve a particular goal? That is, an analysis/compendium of social media sites from NNTP to Parler and the pros/cons of various methods? A book? A report? From small scale (e.g., "How to create a social media site", etc.) to "How to best use Facebook to sell XXX, to influence political campaigns, to overthrow governments, to confuse your competition, etc.". A good bibliography?
