Kudos on releasing Yandori!
We have been (low-keep) working on something similar (more from an academic point of view) for the past few years:
This is the introductory article (open access): "Comparison of news commonality and churn in international news outlets with TARO" https://dl.acm.org/doi/abs/10.1145/3603163.3609062
(Allow me a moment of pride for the student leading this project: the paper won the Ted Nelson Award at ACM Hypertext 2023.)
