I found an interesting research paper from 2022 titled Smoothed Analysis of Information Spreading in Dynamic Networks.

The paper mathematically analyzes how information can be effectively spread over a dynamic network while dealing with attempts to stop the information spread. It comes to the conclusion that randomly broadcasting information improves the speed of information spread in worst case scenarios.

I think the fact that randomly broadcasting information improves worst case scenarios is a very useful fact to remember. Often, spreading information more quickly is better. Also, a strategy of randomly broadcasting information takes less time.
