Thank you, @Remah,
Yes, and I don’t want to be seen as overly stubborn in pushing my arguments to make changes to the current feature.
But besides seeing limitations to the usefulness with current design, I also look with the eye of a product owner. The Discourse team have build up very strong convictions over the years on what constitutes forum functionality and how it should be used. And - being undisputed experts in this field - they are only right to have these, and push back to stuff they see as not adding value.
However, there is also a risk in being so deeply involved in the subject matter. And that is overlooking how outsiders, newbies perceive the functionality. The term ‘Wiki’ has a well-established meaning, and ‘wiki posts’ are different in that they are a wiki mixed-in with a discussion forum. As implemented, it has become an intertwined concept that requires extra steps that make it work (locking the topic, creating the Talk thread, etc), and even then one cannot get the Wiki-only view. By using the term ‘wiki’ you raise expectations.
The UX issues are very real. The extra pomp and ceremony to make all this work, are not necessary.
As what is logical functionality within a discussion forum, I have to note that Discourse team is stretching that definition to the maximum extent on their own forum. Besides discussion forum it is used for Product documentation and Help manuals, Issue management, Release notes, Module repository (plugins, themes, etc.) and - on every forum instance - even Page and Asset management [1].
This ‘dogfooding’ is no problem (I am a fan of dogfooding a product). As an admin I can live very well with that, but it is worthwhile to evaluate how not to force these ‘special uses’ on the end-users.
[1] I am refering here to topics that become the FAQ page and “Assets for the site design” in Site Moderators category, and to which our admin Samuel Klein (a 3 term Wikimedia Foundation of Trustees member, btw) remarked (and I agree):
