Google talks about using over 200 ranking factors so I think a correlation this high with a single factor is actually quite interesting. Especially given that we are seeing a correlation with a model that is undoubtedly more naive than what Google is actually using.
It is also fascinating to see this much correlation with an on-page factor which is entirely in the webmaster's control. Previously the highest correlations had been with link metrics.
YMMV but this research is interesting to me as someone who works in this field.
