I think the title says it all really.
The resource-recommendations tag is very broad, and could really include anything. We have more specific tags for areas where we're happy to recommend things, but should we really have such an ambiguous tag inviting all kinds of off-topic content?
Doesn't the resource-recommendation tag contradict the resource gathering close reason?
What kinds of resources do we want to recommend, and what kinds of resources do we not want to recommend?
