I tried to search for a similar question, but can't find one (yet).
Here's a scenario:
Someone asked about "How to build a SQL query to get count and blah blah blah..."
Someone else answered with a nice SQL statement that has a "group by" statement which seems "logically inevitable".
I proceed to add a tag group-by. I did that on the basis that someone who searches for group-by will be able to find this post useful, just as I did. My concern is, it wasn't described at all in the question, nor was it implied, unlike sql and count.
What is the community opinion?
PS: The scenario above is a real one here. And the one who answered it nicely is Jon Skeet.
