The entropy analysis revealed three distinct eras. Now: what happens inside each one?
Which themes travel together, and which ones compete for airtime?
Themes don't operate in isolation. When a conversation goes deep on Pandemic Response, does it also tend to engage with Equity? When AI surges, what retreats? The correlation network maps these relationships: solid green lines connect themes that tend to co-occur (allies), while dashed red lines connect themes that trade off against each other (rivals).
The real power is in switching between eras. The alliances that defined the Pandemic Pivot look nothing like those of the AI Reckoning. Ideas that once traveled together may have drifted apart, while previously unrelated themes may have found new common ground.

What the Data Reveals
The strongest overall alliance is between Pandemic Response and Open & Digital Learning (r = +0.42): when SLL talked about the pandemic, it consistently talked about open educational resources and digital access. The strongest rivalry is between Pandemic and AI (r = -0.33): these two dominant forces almost never co-occur in the same conversation, suggesting a clean narrative handoff rather than a gradual blend.
Switch to individual eras and the network rewires. In Era 1, Innovation was the universal connector, allied with nearly everything. By Era 3, AI & Emerging Tech occupied that hub position, but with more rivalries than Innovation ever had.
