Question for CB and Ms. Hofschneider:  I'm curious to better understand how this system determines the "highest rated" comments on any given CB article.  For example, it appears obvious--based on the comments submitted so far about this article--that the "highest rated" comments clearly are not based on the number of "likes" each comment receives. 

I have also noticed over the past 24 hours that the "highest rated" often change each time I refresh this page.  And to my surprise, the current most highly rated comments seem to be older ones that were among the first to be submitted, and which make what I regard as conventional pro-rail arguments.  

This was not always the case as more comments have been added.  In fact, it seemed as if comments that questioned or opposed completion of the rail project clearly outnumbered those favoring completion, and that still appears to be the case now after 72 comments have been posted.  

So please help me understand who or what determines this.
