It should be noted that, on a forum such as this, the “view” will be dominated by whatever the participants choose to discuss. If people choose to discuss Bill’s ever-repeating parade of vacuous ID talking-points, for example, then that will dominate. The only thing that can be done, is to yourself avoid discussing some topics, and to discuss others (if you can find somebody else willing to discuss them with you).
If you want the GAE discussed, the only thing you need to do, and the only thing you can do, is to discuss it yourself, in a sufficiently informed, coherent and interesting way that people want to discuss it with you.
AFAIK, the Discourse software has no facility for “Side Porches”, just Side Conversations, which are already frequently employed on this forum (including on this very thread). If somebody wants the former, they will, necessarilly, have to put in a feature request to the developers.
