Forums are great for Q&A, but for howtos, articles, and non-discussion content, they are a mess and will always be a mess without an extremely active and extremely heavyhanded moderation-as-curation approach, because they lack the rigid structure needed to make content naturally discoverable and easily browseable without search.
They are not a good substitute for a wiki or a curated examples repository, and they are a hollow shell of what the v1 examples repository had - detailed, easy to find examples organized by the specific application - something that most software happily provides for nginx and/or apache, but is now near impossible to find for Caddy.
The 1.x examples were curated into alphabetically sorted directories by application. Making it self-organizing documentation where you never have to search, never have to rely on individual users to title their posts correctly, and never have to guess which of the 5 different posts is the best one to follow.
That’s infinitely more useful, because I can see what applications are going to be largely painless to set up, quickly grab the example, and go from there, knowing that the info there is trustworthy enough that I will be starting at customization instead of initial configuration.
A forum badly imitating a wiki gives me none of that. It’s not curated. It’s not organized. It competes with itself to add confusion where it should be creating clarity.
The official docs are full of examples at the bottom of every page, there’s a “common patterns” page which covers many overarching topics, etc. I truly don’t know what else you expect in terms of examples. It’s all there. You just need to read it.
