When faced with a simple question, some users respond with comments that say something like, "You should have Googled it" and nothing else. These are often upvoted a few times as well. Is it appropriate to flag those comments as noise, or respond with "No, it should be part of SO as well", or should I just be ignoring those comments? Perhaps there's another option I'm missing as well.
An example: in response to What is the third value in CSS padding? the first comment is "Really? Google couldn't answer this one for you?"
