This is from 2000. Off topic, but it would be interesting to a predict plausible "next posts" from a given HN user. When I see some interesting but random seeming post, like this Gelman paper, I often try to infer the context behind the post. Is there something in the zeitgeist that makes this post more relevant today? Or is it just noise? The user-posts predictor would look for topics of interest, sources of interest, and trends in topics. Is the user onto something? Should I pay attention? The worst/best part of HN is the interesting noise. I am sure there's a Gelman paper on that.
