SourceKibitzer was an initiative to collect and measure programming metrics from Open Source Java projects hosted all over the web in order to get an idea about the quality of code, member activity, development process and project size. SourceKibitzer is now defunct and the organizers have moved on to other projects. Historical data from SourceKibitzer is available from the FLOSSmole project.
