Do messages spread widely also diffuse fast? Examining the effects of message characteristics on information diffusion
作者：
Highlights：
• The study explored what messages are shared widely and fast on social media.
• The data included a year-long corpus of all the original tweets from the CDC and the diffusion of each tweet for six days.
• The findings revealed distinct effects of intrinsic message characteristics on the size and speed of diffusion.
• Negative emotions drove the information to spread fast, while positive emotions slowed down the diffusion.
• The study provides new insights into the temporal dynamics of information diffusion on social media.
