In all honesty I have been using Yahoo! for fantasy games since maybe 1999-2000 or something like that and I can say over the years there have been numerous changes. Some of the items that have changed have been things I have mentioned to customer service, and there's been plenty of great changes. A minority of them have been changes maybe I didn't prefer, but nothing that has interfered with the gameplay.
Some of the requested changes are things that are just not going to happen, sometimes because of the technology and how complicated they are and other times just because it's likely not something a majority of players would like.
To me, this setup is great and very transparent and I hope it helps their services.
