I think this would be too analytical. Overthinking a problem or overthinking the solution to it (I have that overthinking mind too). Though it's just an idea, it can be perfected in the future.
There are some very valuable comments people can leave even if they don't read the article (scary, I know) and perhaps if we see an article we read 3 days ago and just remembered a comment we wanted to leave, but we forget the exact details of the post, then we could fail the questionnaire or be frustrated.
Just having to use the time to answer a quesionatire to leave a comment is annoying and frustrating itself. Though people could get used to it, it would change the landscape though. Imagine non-computer savvy people or foreign language speakers having to deal with this. Let's not punish the weak!...or rather create hurdles for them to come on such an awesome platform as steemit!
