I think it would be very handy if we were able to see the tags associated with each question listed in the "Related Questions" section of the "Ask a Question" page.
Use case
I was asking a question titled "Return statements in Ruby", intending on getting feedback for best-practices for ruby return statements (as they are optional).
Return statements obviously flagged tons of not-aptly-titled questions, most if not all of them had nothing to do with the particular syntax of ruby. Instead of being able to visually filter the non [ruby] tagged Related questions, I had to question whether or not this was a dupe and click on several of them to find out if they were related (no, they weren't).
Having the tags there would have saved time and reduced duplicates if my question had already been asked.
