This is the place where you can ask where is the more appropriate place for a topic you have in mind: maybe there’s already an ongoing discussion relevant to that topic, or someone can guide you to the right category.
If you’re wondering about a missing category, you reached the right topic: please describe the category you have in mind and why it should be created. Each category requires one or more hosts who will be in charge of organizing, facilitating, and moderating it so that it remains active, relevant, and welcoming.
It was suggested to me that there’s a category missing to invite non-technical talks related to ActivityPub and its milieu. Something that would be welcoming to academics, journalists, and a public curious about the purpose, history and outreach of the ActivityPub community. For example, the following topics could belong there:
I removed the word “implementation” from ActivityPub and added a description for Programming to help people choose the right place for their discussions: the former relates to improving the specifications while the latter relates to implementation issues of the specs.
