I just now came across this questionthis question.. the comments (well, answers) made there reminded me of this discussion and made me feel uneasy.
While the question is indeed pretty "dumb" I wouldn't laugh from the sarcasm if it was my question.
The thing is, the sarcastic answers got pretty high score, luckily The Skeet came to the rescue.
Bottom line: this sarcasm is exactly the thing that can drive newbies away - there's no offense and no insults but still.... coming as high upvoted answer it doesn't look good.
Personally I might post something like the "cup of tea" as comment adding smiley to reflect it's said in humor - obviously that's not what the OP meant anyway and he should clarify his question.
