I guess I did, and I still do - I didn't see any irony there, just analyzing and poking fun at the original article. I might have read it a bit to quickly, but what I got out of it was that kids won't make you any more or less happy than you were: The original article stating that you will become unhappy, and this rebuttal saying that your happiness is determined by yourself, not your kid.
So my conclusion was -- though poorly worded -- that, if I don't really want kids now, I certainly won't be happier if I DO try to get one now.
