A few years back I thought this was a good thing. The constant barrage of information through link aggregators (hn, reddit) and various blogs led to my aquiring some, mostly slightly more than superficial, knowledge about many random topics, which does have its upsides. On the other hand, it somewhat diminishes the time and energy available to do or learn something actually productive. That said, the random information I consumed isn't really the kind of "junk information" of the linked article, it's just info that's only partly - often not yet - relevant to me.
But it has comparable effects:
The vast majority of the online content you consume today won't improve your understanding of the world. In fact, it may just do the opposite; recent research suggests that people browsing social media tend to experience “normative dissociation” in which they become less aware and less able to process information, to such an extent that they often can’t recall what they just read.

This is something i experience often.
As an example, this article titled: "No ones buys books"

It's not junk - to the contrary, it's an interesting piece. It just got very little relevance to me, personally. I don't work in publishing, i'm not an author. It's satisfying to learn some interesting tidbits, but on the other hand i really had trouble concentrating enough to read the whole piece.
