"eat our own dogfood" some more

Use PieFed for announcements, discuss ideas and Pull-Requests. The things that spill over from Codeberg into the Matrix chat and would benefit from a threaded conversation. It's a two-edged sword. We'd be approachable more easily and grow a community within the software we use. Of course that'd be open to lower quality and random interactions. Either we're fine with that, or we better skip that idea. Main benefit: We'd be forced to implement something that makes PieFed better at that kind of task. Like limit communities to trusted or PieFed instances, do some membership handling, and/or mark accepted answers like on StackOverflow/Discourse, use tags/flairs to indicate open/closed/archived threads(issues) … (We could just test the waters and see if that’s a better way to communicate and in doubt switch back to the current setup which works well.)
