We have Netflix Fan and My Netflix Journal (actually Manuel Villanueva's) that brought to my attention the practice of "throttling", or Netflix purposely delaying or shipping discs lower in your queue, violating the "unlimited" part of their service. I did have the problem of delays in shipping a week or two ago, but now have been waiting for Friday Night Lights, a movie I've had in my queue since before it's release on video...
Also, there's Blog THIS, Pal!.
