The Edmunds group has a very poor interface. It provides nothing but a single thread, just one that goes on and on and on regardless of actual topics. That provides fruitful opportunity to conceal vaulable facts and to twist the words of others. Also, their policy prohibits links to outside automotive/hybrid websites, preventing references to helpful content.
Needless to say, there is a small group of people that takes full advantage of that.
Here, we have a much much much more friendly interface and usage policy. That scares away those that like to twist facts and use vague references... because they know if you repeat something enough, people will eventually begin believe it.
