Nice post. Couple things, minor points. I would call this 'social exchange' not 'collision'. And likes, follows, RTs, etc. play a signalling role that is analogous to prices in markets. This way, social media dynamics (including monetised mechanisms such as Steemit) can be explicated through the Austro-Virginian political economy lens, which is useful, I think.
