Right now, in addition to this being the top story on HN, it is is on the default reddit front page at #9 and rising. It's also on the front page of the New York times website, and also in the top three headlines at news.google.com. Google reports 25 articles most being published in the last hour.
By these measures, it seems to me that a lot of people are rather interested in the story.
Now, I understand that you may not consider "the population that consumes its news on the internet" to be equivalent to the "general public". But any argument about that question is a much larger one than an argument about the public's interest in this particular story.
The fact is, even amongst all of the tabloid trash real news stories do matter to people, and people who consume cotton candy celebrity media for entertainment can also be consumers of hard news. The existence of one doesn't preclude interest in the other.
