I was looking for this question, which I speculated was tagged parshat-shelach. I clicked that tag from another question and didn't find my question. So I searched for my question, confirmed the tag, and then clicked on that tag from that question -- and got a results page with four questions, not including the question I just came from.
The four questions that the tag link does find are: Calling Hoshea 'Yehoshua' before his seeming renaming, What would have happened if the sin of the spies never occurred?, Is there any evidence of Nephilim?, Rashi in Shelach 8 days c'neged 8 strings of tzitzis. I've been unable to determine what those four have in common that my target question, Why didn't Yehoshua give a good report immediately?, doesn't have.
Anecdotally I've looked at some tags in the past week or so and thought "hmm, I thought there'd be more questions about that". I don't think it's just about this tag.
