That's a lot of expertise and I bet nobody in the industry watches them.
This could even possibly be true.
I would argue that most programmers and designers are a self-centered bunch who think they are so special in their thoughts and ideas that they don't need advice.
And then there are those who like to make mistakes, like those who use their position in industry to gain their own experience and thus produce redundant mistakes that their colleagues have made in the past.
Ego sucks ass advice unless you're experienced or respect the knowledge of the experienced veterans without having to like them!
That may hurt the developers, but I'll say it. As a customer, I'm not interested in your ego, but whether I enjoy your product.
Edit:
I'm only interested in ego for developers who don't sell their game or mod, in which case the person might be interested in boosting their ego.
And if I like their work, I say so, and if I don't, I criticize with the utmost respect, unless I can tell the person has thick skin and doesn't mind a few nicely meant, harsh words.
