People asked for a similar users tool back in the early days of HN: http://news.ycombinator.com/item?id=701 http://news.ycombinator.com/item?id=701 And recently, too: http://news.ycombinator.com/item?id=1036247 http://news.ycombinator.com/item?id=1036247 How does this particular tool work?  It's based on the threads a given person comments on, who else comments on those threads, and how the topics and terminology of threads and comments relate to each other.  Karma on the relevant threads is used as a subtle authority metric.  Incorporating voting relationship histories would almost certainly make the tool better. Particularly at finding interesting (and not merely similar) stuff. That said, it'll be interesting to hear what folks think.
