The reachability of any given tweet is partially constrained by how many people for whom it makes immediate sense. I don't mean the semantic meaning of the tweet, but the broader legibility, interpretability, intelligibility, relevance. Like "wtf are you talking about".

(1) Most tweets say very little but just link or refer to a couple of things you already know in a clever way.

(2) It is impossible, in this format, to say very much at all, or anything very original. Too short, too quick.

(3) If you read wide broadcast tweets too much you marinate in a weird wide broadcast headspace.

(4) Low dispersion in view count for a successful poster means high audience affinity or low originality.

(5) Posters tend to be bad at predicting when their own tweets blow up (maximal self affinity).

(6) Successful posters maintain role-continuity and context-continuity. They enact, embody, reify, produce a character.

(7) The capacity and willingness of an audience member to parse, engage, grasp, consider more than one frame can be selected for over time.
