What comes to mind for this Hacker News Simulator is the modern equivalent of da Vinci's sponges: an ink blot which you can use to come up with completely new and novel ideas by forcing unexpected connections. And because the topics here are in some way related to hacker news the result could be filling in enough blanks to produce something newsworthy (i.e. an actual good idea instead of a garbled markov chain.)
To make the most sense of this, it helps to read Richard Wilhelm's translation and annotations of the I Ching. If you don't read German, then Cary Banes's translation of Wilhelm's translation is pretty much the only one out there. Unfortunately still under copyright (ha ha... on 5000 year old document). But it is widely pirated on the web.
I often wonder if the random "predictions" of the I Ching were originally just a way of studying. There are 4096 different transitions to look at, and approaching them systematically would be painful in the extreme.
I've spend some time to see if the transitions actually make sense and from what I can tell, they do (modulus my ability to fool myself into seeing reason in things that have no actual reason). I wish I had enough patience to actually study it ;-)
