Planet Scala's code has been moved to GitHub, motivated by the creator DRMacIver's lack of interest in maintaining its web frontend. DRMacIver views Planet Scala primarily as a feed aggregator rather than a web-centric project and seeks collaboration from those more invested in web development. By hosting the project on GitHub, DRMacIver aims to attract a distributed group of programmers with diverse skills to contribute to its development, leveraging the collaborative nature of the platform.
