Well, I occasionally read CNET, which has the domain "news.com".
But, the fact that domain points to CNET rather than something more well-known (and general-interest) is itself great evidence of the unimportance of general domains.
Also, CBS Interactive bought CNET more than a decade ago, and the news.com domain with it. CBS has kept the domain pointed to CNET rather than, say, having it point to cbsnews.com.
facebook.com maybe as well although it has given the word a new meaning.
I don't, because those names are almost always used by major corporations and the like, and I almost never am interested those websites.
Probably because those extended TLDs are shunned by many users. I know that I tend to avoid sites that use them, because such sites tend to be ones that I prefer to avoid.
There are a few such sites that I'm comfortable with, of course, but those TLDs are a bit of a red flag and sight unseen, I assume they're not for me.
