Yes thats interesting. In fact stackoverflow is an example of what I mean. Even if the service provider does not choose to use stackoverflow for issue tracking, people will still ask questions (and indirectly report bugs) because of the community. Any technical service provider who cares about users would be stupid not to monitor stackoverflow for discussions about their product and jump in. However, you are right, stackoverflow is not for the type of issues we are talking about, like "I cant login", "This form gives me an internal server error with this input" etc...
