After deploying a report in Sql Server Reporting Services 2008, one discovers that the Report Server has the ability to display an informative Report Description next to each report. That report description can be very handy for users when there are many reports inside a given folder.
This realization leads right back to Visual Studio. Suprisingly, though, Visual Studio does not offer the opportunity to set report descriptions before deploying the report. There are many features of Reporting Services that cannot be set prior to deployment, such as Subscriptions, Cache behavior. It makes sense that the developer of the report would not need to be concerned with the way in which the report is used. Plus, when deploying a revision to a report, you don't want to override any of these settings that govern its behavior. But in the same way that good code needs comments, reports too benefit from as much descriptive clarity as possible.
