Not to compare github or gitorious but meego code is available in gitorious, There might be contributions to meego code once CSSU for harmattan picks up. So I feel it would be better if the repositories are in gitorious. Otherwise devs need to learn how to use both gitorious & github. It's not too late now to re-visit the host location.
As someone who just today put his project on Nokia Projects I ask: why github (or gitorious or bitbucket) and not Nokia Projects?
