I don't see it, for instance, here at Less Wrong.
I do sometimes get mildly annoyed at people linking to a generic news site about some research (nytimes, etc.) instead of digging up a source as close to the original as possible.
It may not be "blogspam" proper, but it's research or tech being summarized by journalists, which tends to be less accurate than the original source.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
