Yeah, that’s another reason why I wanted these queries to be treated as more than a “cool tip”. Every custom query merits its own discussion and success/failure reports.
Including many of these queries in Discourse core would be great, but surely there will still be a few niche ones left out that ought to have space of their own.
A special tag or variety of the Solved plugin could be nice here too, i.e. to mark queries as “Tested” (or “Reviewed”, or “Safe”).
There could also be a “Query Author” badge.
