I can assure you that just because some thing is attacking does not mean it isn't constructive. Every comment I've seen that says "You could do better/It would be better if you..." are all constructive and it's up to the builder if they want to listen to it. Have you seen the elongated reviews Dotrobot posts on nearly every one of my screens? It can be harsh sometimes, but there is no way one could think that to be non-constructive....as with all the other "crossovers".
