Well my post about the Time Warner's move to charge variable rates for high speed internet garnered more comments in a few minutes than I ever typically get on any post.  Lots of good points were made and questions asked in those comments, the most obvious of which is how customers are supposed to tell how much data they're pushing through Time Warner's "tubes".  Ben offers some excellent tips for how to track your internet usage here.  I'm sure there will be much more on this story to follow.
