Rominl,
No, not really. Those forums discuss mostly items related to "How do I run this game on this OS?" and the like. I am more concerned with Enterprise level software and hardware questions and answers. Things like "How do I move an Exchange server site?" or "How do I configure Terminal Server?" or "How do I setup a cluster in Win2k?". You may say, well, these things can be found elsewhere and that would be true, but I find that a forum brings out many other people with many different experiences. Those varied experiences are more valuable than some "white paper" from the OEM could ever be.
