In your opinion, should project teams hold meetings with their community?
I believe so, but not to the point that they have to consume the time of theirs and their community. There should be normal communication from any platform that they support and with their community so that they can bring what are their thoughts toward something that they see about the project.
It's very important that you'll be having conversations with any representative of the project and with the community. That seems to be a good relationship between them and its community.
