Speaking as someone who is a noob to the board; My experience thus far is the boards are friendly and helpful, there are some rather extreme opinions around. But I think it unfair if individual opinions of the extreme variety should reflect on a forum as a whole.
As such apart from thinking people who liken George Lucas to a Nazi as an idiot, I don't think that is at all representative of the forum. Or to put it in the extreme analogy some of the Lucas haters would put it, does a serial killer reflect upon their society as a whole? I'd say the answer has to be no.
Lucas has of course lost the plot (which isn't new to him, seeing as he seemed to of completely of mislaid the entire prequel plots), and individuals failures to recognize that says as much about them, as those who seemingly want to kill another human being over a film franchise.
For me I have generally found the threads I've looked at interesting and informative, with a number of interesting viewpoints represented. The fact Adywan and Harmy are both regular posters here speaks volumes as to the regard the forum should be held in. I for one am very grateful that there are some very passionate fans here, who have done some wonderful works for the community, and I think the forum has been a massive force in that.
I can only speak for my self here, but although I'm part of the Star Wars community (I'm a moderator over at Lucas Forums). I am affraid I would have to confess until earlier this week I kind of knew of your existence but had never checked the forums out. As such generally I don't think you can have too much of a notorious reputation, as "infamous" boards tend to be more quickly known than good ones.
Just my 2 cents...
