When you’re working on any project that’s Fedora related, and you need to ask questions of a team, the default should be to communicate the question on a public forum. If the conversation isn’t open and transparent, there needs to be a good reason why not. “Default to open” is a pretty well-known mantra in FOSS so this shouldn’t be too surprising or controversial.
There are certainly times where private discussion is warranted. Dispute settling (not to mention disclosure) is often best done privately. If you have to relate personal or security sensitive details of some sort, putting them on a list for eternal archiving may not be appropriate. There are other good examples out there. But in all these cases, it’s important to minimize their impact on public communication. In other words, strive to filter those bits that are best kept private, and keep the rest in an open and transparent discussion.
Every communication of an idea, discussion of implementation details, and canvassing for opinions is a chance to involve others in what you’re doing. If you keep it private, you’re missing out on one of the chief benefits of the open source way — involving others and enabling them to help you as well as themselves. The question is never “Why does this discussion need to be open?” — it’s “Is there any good reason this discussion shouldn’t be open?” And if necessary, as a follow on, “How can I separate the private part of this discussion so it doesn’t keep the rest from being open?”
As the Fedora community continues to grow and spread, we need to continue to teach this aspect to new members — and those who are experienced must lead by example.
