Macromedia Public Bugbase?

Macromedia has been contemplating the idea of a public bugbase for its products. I have two questions:

  1. Is this something the ColdFusion development community would consider useful? If so, why?
  2. Does anyone know of any other companies who have public bugbases for their products (not open source projects)? If you have used them, how useful did you find them to be?
