[Aeolos]

When I moved my open source project to GitHub, contributions skyrocketed by roughly 10x. I attribute that to three things: - contributors need to learn a single workflow to submit patches to any open-source project:fork and submit PR - contributors already have a github account, so a significant barrier is removed for flyby contributions (no need to register a new user account to a mailing list / bugtracker / or both for each trivial or non-trivial fix.) - network effects and improved visibility

Each of those may appear small by itself, but they combine into a significantly better experience for contributors.
