Welcome back. I moved this into a separate topic since it seems a bit different. We could easily solve this by having a high-quality tag. The issue becomes the maintenance and disoverability of said tag.
What happened in the original thread is that the high quality guides ended up never being used because it requires actively choosing them and nobody did. The suggestion there is to have an archived docs category.
For this one I feel like it will suffer from the same problem. But creating a tag is totally fine. Can see after a while if it gets used. We could even add it to the forum nav bar as “best posts”. But idk if that would be better overall.
Discourse can also list the top posts (based on views and other metrics such as engagement). I think this is better in the sense that it already exists and is automated. Anything else that requires on human curation feels tough to do.
But it doesn’t stop anyone from creating a meta-post named “best forum content” and linking to various posts.
