Preface: I am not sure how possible this would be considering the forums use AnswerHub.
Right now there is really only 2 sections to post things to the community forums. QA and Ideas.
The QA side really only works for specific questions with intended specific answers.
The Ideas side supports a more open discussion of features and ideas.
This ends up leaving a pretty big gap for questions, comments, concerns that would be more open discussion based. It also encourages people to only participate in the community when they need something answered or feel they can strongly answer a question. The community slack makes up for this in some regards but it is much harder to catch up on interesting past discussions.
Examples:
How are other developers handling caching data pulled from PF locally in X framework and on Y platform?
Opinions on how to handle network / server errors?
Discussion related to new data api, guilds, upcoming features x, y and z.
Anyone have any cool tools or techniques they used when building custom tools?
