S. Somasegar recently blogged that Visual Studio 2005 bugs logged via Connect that were fixed in SP1 are now listed. (listed here: http://connect.microsoft.com/VisualStudio/content/content.aspx?ContentID=4324).
Attributing Connect feedback to fixes is a huge step in the right direction. It allows users to follow their feedback through fruition. This is wonderful because--at least some--feedback won't fall into a black hole and give user's the impression that providing feedback via Connect is pointless.
Let's face it, logging bugs can be a thankless and frustrating process. The unlimited potential combinations of hardware and software installations sometimes makes reproducing bugs very difficult. There's nothing more frustrating than seeing "can't reproduce" for a bug that you encounter daily. This list provides the feedback to users that Connect is indeed a useful tool.
