I put an “importance” score on my posts: this weights the topic of the post.1 The scale goes from 1 (“applies only to Gavin’s life”) to 10 (“applies to the entire possible future of all life”). So, superexponential: a “10” topic is much more than a trillion times more important than a “2”.
Anything “4” or above could affect you, might be something you should know, as a generally optimising or curious or altruistic person.
It is an enduring mystery to me why my interest in a topic is not more correlated with my own estimate of its importance. ¯\_(ツ)_/¯
