@cdevroe @pfefferle I'd prefer having something like a setting that determines per author profile which of the author's content gets represented in AP. Such categories are not meant imo for outside consumption, it's just an internal filter for me to manipulate various content streams. I do have categories meant as externally communicated structure. E.g. a post could be in Culture and Messages or RSS-only. The first is a content category, the latter are 'channel' categories if you will.
