>When I last checked, of over 10k posts, it only uses a few dozen to calculate that score, so it is about as reliable as dowsing.

A few samples are sufficient when the signal is strong enough. The time spent pie chart is definitely more what the user has been doing recently.

Overall, not everybody comes out the same, Pedantry is strong which I'm not really surprised about for a forum like this, but there are definitely personality traits of some users of sufficient magnitude that you can guess what the result will be.

Obviously this won't be a representative sample of HN because it will vary by time of day and topics under discussion. It's sufficient to show that the community is not entirely homogeneous.
