• The paradigm shifts involved
  
  
  • Reader: move towards maintaining overview and handling end-user
    
    
    • Reader specializes in handling just the overviews, which simplifies code and reduces the complexity/cost of I/O subsystem
      
      
    • Reader retrieves articles from spool server by fetching Message-ID from overview and iterating through spool servers looking for it
      
      
    • Reader optionally caches articles, potentially increasing performance for second-hit while lowering actual bandwidth requirements
