Welcome to our world David Little.
Sometimes what seems as negative commentary is constructive and leads to further improvement but once in a while it is just negative.
On the whole you will find us all a very supportive bunch on here not just towards Ady but to all the editors and contributers who gather on these boards.
I hope if you get the chance you can have a browse around and dip your toes in the various pools around here and dive in with some ideas and observations of your own.
