Seriously, how hard can this be? I can't imagine that there is a whole lot to creating a new forum.
Let me lay it out in a way that might be more convincing to those who have the ability to make it happen.
Programmers like to talk to other programmers about programming. There are many, many programmers among Anandtech Forums members and visitors. If you provide a programming forum that is easier to use, more programmers will talk about programming on Anandtech Forums. That means more page views, which means more ad views, which means more ad clickthroughs, which means more revenue for the site. Also, and this is a critical point that is to be ignored at your own peril: Programmers make more money than the average person, which means they have more money to spend than the average person, so why not let them do it through your site instead of someone else's?
Seems pretty obvious to me. If there's something I'm missing here, feel free to educate me.
