[...] this is a great example of overcoming something that we call "problem A, problem B" paradox.
So you've got a group of people coming together, and they're all trying to solve the same problem (problem A) and they're really passionate about it. And then, you've got this problem B thing, which is that you got a bunch of people with different views.
And they may seem to be conflicting, and it seems like a paradox: the same differences that we need to solve the problem are getting in our way. But if you think about it as a paradox, you can get through it.
You think: OK, we've got all these differences. You have to identify the differences that actually are going to move us forward and those that are getting in our way.
And the differences that are getting in your way, set them aside. Push them off to the side and focus on the ones that are helping you move forward.

Well, I noticed that at first everybody was saying "Yes, but this is my idea".
And as we got closer and closer together, it became "Yes, and".

IMO this is an important lesson to learn if you want to work effectively in a community project like Debian.
We talk much about diversity, and the added value of diversity in our project.
But diversity also means that to converge towards consensus is difficult and requires a specific set of best practices.

A little thing like saying "Yes and" instead of "Yes but" could be of help. Words definitely matter.
