quotes that never were
closest proximity: "I have the advantage of
knowing your habits, my dear Watson," said he.
"When your round is a short one you walk, and when it is a long one you use a hansom. As I perceive that your boots, although used, are by no means dirty, I cannot doubt that you are at present busy enough to justify the hansom."
"Excellent!" I cried.
"Elementary," said he.
Is it “Elementary, my dear Watson”?

events that never were
"Street style shooting in Oxford Circus for ASOS and Diet Coke. Let me know if you're around!!”
"Apparently theres a shooting at Oxford Circus, gunmen on the move. We've been told to stay in”
“Shooting in progress in Oxford Circus? What?”

“I will mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate, only love can do that.” – MLK Jr.

shorter phrases are more popularphrase variants within the same cluster on MemeTracker

• imperfect copies are made• choose to copy either from
source or from another copy• more likely to choose more
recent copy to copy from

what if copies are not derived from copies? When quotes are found on blogs directly citing
the source (e.g. NYTimes), there is no shortening over time

How are memes affected by network structure?
![Page 18: Meme spread in networks](https://reader035.fdocuments.net/reader035/viewer/2022062501/568165a1550346895dd87ef2/html5/thumbnails/18.jpg)
network structure and meme mutation subset of MemeTracker data contains network
information 9,208 nodes and 61,511 distinct edges
in-degree of a source node is positively correlated with percentage copies made of the source that mutate it (r = 0.45)
in-degree of copying node is slightly positively correlated with probability that it will mutate what it copies (r = 0.14)
betweenness is positively correlated with sd(length) of copies (r = 0.43)

Fidelity in the mainstream media & blogs
Proportion of derivative typesoccurring on edges
Types of alteration amongphrases that are not exact copies

summary information changes as it propagates through
a network multi-step diffusion is responsible for change the change can be modeled as a simple urn
model the characteristics of nodes (mainstream vs.
blogs) and their position in the network correspond to different amounts of change
