actually, C&G is among the tamer internet sites in terms of negativity in posting, be it forums or comments. A lot of the comments posted even on autoblog and car and driver comments are quite nasty. or stupid. CNN's comment boards are among the nastiest (and most entertaining) on the net.
one thing the internet has done, through our anonymity, is allowing millions of us to get our real thoughts off our chests and into the public forum. It turns out this nastiness is what lots of people are thinking all along, the internet just means more people have access to what we are thinking.
it might not be the best thing, but mano, imagine our parents and grandparents and their opinions and no way to express them to validate them. at least even with internet debate, people's opinions are challenged by someone else, even if not in a civil manner it maybe keeps people in check more in terms of thinking they are right all the time.
I know at least on topics politically, some things i have opened to rethinking because of so much discussion about them on the net.
Its definitely a new communcation standard that IMO has changed our culture a bit.
I just thought the article's stereotyping of the typical posters was kind of funny. LOL.
