The point of the thing for me was that the Crimson analysis showed no change in rate of decline since 1900. So there is a need for more examples over larger timelines before we start modelling, perhaps. The analysis also seems sensitive to the mapping of words to categories. Some kind of robustness analysis to this sensitivity would also be interesting to see.
