I think your graphics would be more accurate if #1 didn’t split Kanye’s original Tweet into 5 separate Tweets that then distribute to his Followers…
The structural advantage of digital media (especially Twitter) is infinite replication at zero marginal cost or effort. In other words, a single Tweet is available to infinite users without the need for reproduction.
Your #2 graphic is a bit more accurate, splitting that Content Producer’s Tweet — having been consumed by Followers — into iterations that’re then disbursed into the Twitterverse. For example, when Kanye’s Followers consume his Tweet, they may Retweet/Quote/comment, which creates a derivative of the original, which then increases the probability of discovery by the broader Twitterverse.
