If one reads the article there's a few interesting points-- it includes some statements by Mossberg and info on his book which will probably include some thoughts on Facebook.
I try to at least skim stories before commenting on them which is the only reason I opened this one. The title reads like cheap celebrity journalism. Something more fleshed-out, like an interview going in depth about his thoughts on Facebook and tech's impact as a whole, leading to his book, would've been more "NYT worthy" IMO. And a better title.
Also, mossberg is a journalist. I was under the impression that journalists being the news themselves is bad journalism. Isn't that why most journalists go out of their way to not to be part of a story?
If rupert murdoch, in his war with facebook, pressured mossberg to close his account, that would be news. Otherwise, this is just the nytimes and a journalist creating news, not reporting on news.
I may be misunderstanding your claim that it's "detracting from any previous viable points". What points are you referring to that this detracts from?
