I have to say that I have maybe visited that site on maybe three or four occasions, ever. I've no idea what their editorial stance was, or what it is now intended to be, moving forward.
What difference does it make where the new owners reside? I don't see how that can have any effect on such a large site. What the general public rarely understands is that owning, operating and administering a discussion forum is rather akin to herding cats. Deaf cats. Cats with long claws. Cats with voracious appetites. If a forum is allowed to grow, willy-nilly (and most are), then whoever is sitting at the helm is actually just along for the ride, more than anything else.
What is wrong with targeted advertising? For anyone who gets all indignant about a Web site owner using contextual advertising, I have just one question - when you go to work each day, do you do so with the anticipation of being compensated for your labors, or do you just volunteer your time? How many of you spent your life working for no pay, yet managed to provide for yourselves and your families? What is so different about a Web site administrator trying to earn a living from those labors? Do you people really think these sites are free and run themselves? I really don't think you want to get me started down that road.
As for any change in what is and is not fair game to be posted on a discussion forum, tread carefully when you start tossing about the word, 'censorship'. People who start howling about their misunderstood 'freedom of speech' rarely have ever taken the time to actually read the First Amendment of the Constitution. At the end of the day, this is my house. And if people want to be welcomed into my house, then they will respect the rules of my house. If they do not, then they are no longer welcome. What gives anyone the right to visit any privately-owned and privately-operated discussion forum with the misconception they can say or do what they please? The First Amendment prevents Congress from abridging free speech. It doesn't say a word about privately-owned Web sites.
I am afraid I am just not familiar enough with that other forum to understand the rest of your post. How does the sale of that forum bring about a sea change in the "business" of the Web? I don't get what that means. How do you think monetization of a single Web site might 'ruin' the Web? I thought that forum had long sold advertising for specific forum sections, so what is really changing? How many Web sites do you visit in a day that are not somehow monetized? I've news for everyone, Web sites can be money pits and if they are not monetized, they are not going to last very long.
My take on it? I hope the original owner managed to sell for enough to make his efforts worth his while. My guess is that he might have been lucky enough to get out whilst the getting was good, which means he ended up taking a bath. I hope not, for his sake.
