This is the biggest issue I have with the community on the site.
Don't get me wrong I love those guys and the vast majority of the content they've put out over the year has been amazing.
However, the moment you say something negative about any aspect of the site, no matter how polite you are, the message will either get deleted by the mods or you will get a bunch of people that will automatically come to the staff's defense and flame down whatever you said. Most of the time those defensive comments are more hostile than the original criticism but apparently everybody is ok with that.
How can somebody improve and learn from it's mistake if everybody keeps telling him he's perfect?
