Methinks he is entitled to his opinion. Methinks also that the thread may cause users to over estimate their looks. If we're all so good looking, then that makes us more average than we realize...
I agree, however calling the thread narcissistic doesn't help in making people feel good about themselves, which ultimately is what it has turned into. I don't think there is anything wrong with having a confidence "boost." Although the comment wasn't directed at one person, its like saying you're obsessed with yourself because you posted a picture on here.
