Working in open source in these modern times is, for me, a lot of fun. The advent of tools like git (and services like GitHub and GitLab), collaborative platforms like Etherpad, and chat services like IRC have made sharing collaborative projects a much more streamlined process than in days past.
But what if members of your team prefer Slack to IRC? Or Google Docs to Etherpad? Is it time to get the holy water and exorcise these heretics from your community? Or can a more ecumenical embrace be employed?
