How does fedora.us differ from FreshRPMS or other repositories?
Many other repositories like FreshRPMS are made by a single person. Fedora can have a lot more packages, and of higher quality, because we have many package developers working together on a common authoritative repository. It is our belief that collaboratively developed package repositories tend to produce higher quality and reduce the chance of clashes. Other examples of high quality collaborative developed repositories that do not conflict with fedora.us are rpm.livna.org and jpackage.org.
