Wow, what timing.
Late last night I had a conversation with someone explaining that Hacker News is not your typical message board -- it's owned and operated by YC and sits atop algorithms developed by some of the pioneers in spam and anomaly detection [1] [2], and it's is also an open dataset -- analyzed and scrutinized -- used by hackers worldwide to train and test bespoke AI.
HN is a live MNIST [3] for anomaly detection.
