We're keeping our code in Mercurial repository on Google Code Hosting and we haven't seen any issues except for just one: a "third-party" developer can't easily propose a change in our code. That's what GitHub is really good at, and we decided to setup a mirror of GanttProject repository on GitHub. We're using hg-git for that and hope that the mirror will be as actual as the main Mercurial repo.
