Typed responses are often "mean" sounding when the writer just doesn't like to type and wants to use the least number of letters possible or doesn't have the time to provide a long flowing explanation with diagrams and color photos. Sometimes what sounds like a funny answer on this end sounds like a put down on the other end. Some people are so sensitive that "Google that" would sound like a harsh beratement. I've seen very few really rude answers but if anyone gets one you can flag it as "Inappropriate". Picking a "best answer" if you get a good one would be courteous since nobody gets paid here and it's a small price for you to pay.
