OK, that's the response of a third-grader in the schoolyard.
It's on the level of "my dad's bigger than your dad".
You came here asking what people thought of your site.
You were given advice on how to make it better... that is the nature of constructive criticism. Constructive criticism is something that can make us all achieve better things: this is why the manuscripts for books pass through editors and sub-editors, for example --- so that those little things that may have slipped by the author can be improved.
Taking constructive criticism as a personal attack and responding with schoolyard taunts, however, is the sign of an underdeveloped and juveline personality which has yet to come to terms with the realities of the world. My comments are not about you, they are not a personal attack, they are a tool for improving things, as any mature-minded person would see.
But like I said, if you're happy to be second-rate when the key to being first-rate has been handed to you on a plate, then it's your sorry choice.
