I agree especially with some of the content providers. They only post here when they spam, rarely get into the other posts and contribute nothing.
I try to help anyone who asks for advice on what little I know and have tried to contribute on things like Acacia, even though I doubt if I made a difference.
But this is an industry and the boards are where the industry meets to discuss issues that are important, educate and learn. Some think it's a place to flame, show off and act like an idiot. They then wonder why they are not doing so well.
Use the boards as a tool, but also build something with them.
