Thanks Ben - this is really interesting.
In addition to being an example of what is possible with nothing more than a change in perspective I think this is also a good example of the fit between a specific 'kind of story' and a structured approach. Like Homicide Watch and, I believe, like state/local government activity, these are persistent stories that are of low interest to most people most of the time, but of extremely high interest to some people some of the time.
I think that the metrics by which the success of structured journalism is judged perhaps need to accommodate that - maybe new metrics such as 'lifetime engagement' or 'cohort repeat engagement' or similar are more appropriate for stories that persist as structure. Chris Amico has written a little on this as it applies to Homicide Watch, which is apparently still getting significant page views long after fresh reporting stopped.
