The forum acts as a collaborative library were members add, ask and comment about their personal interest and research. Anyone benefit for the collective compilation activity which is often way more effective than individual effort.
To me, I think it's a matter of stay on topic and avoid the forum departing from that original foundational purposes.
To readdress the situation, creating the "bar" and "alternative/speculative" sections seems to work for us and most fora. Probably a compromise solution, but at least allows to keep the forum's precious core free from clutter.
I confess I'm not a fan of that sections but, visiting it for moderation purposes, I must admit that sometimes I've found interesting posts. So, probably, the forum enjoys a reasonable good health.
About posting links from "X", I'm not an "X" member and I find useful to find links here with projects contents.
War in Ukraine started as totally off-topic to the forum, and to me we have too many off-topic posts from it. However, since the Ukrainian battlefields are being used for military tech testing and development, that specific information is relevant here.
