why do you say that, because it isn't a press release or some startup garbage? It's old news, but still news
Blogspam is a term used to indicate that the article in question is just a rehashing of the real article that adds no additional content or insight, the sole purpose of which is to increase pageviews of the blog.
Yeah, I've seen those links before, but I don't see how this article applies, this is not an excerpt with a link to the "real article" it's basically a tutorial.
Updated my comment with what is presumably the real article.
Even so, this looks like a more accessibly explained tutorial, with original screenshots. I don't think you can legitimately call that blogspam.
