I think people have different definitions of blog spam and it's a matter of taste. Personally I began to grind my teeth after the first cliche-ridden paragraph ("cliche-ridden" again being subjective, but the "there should be a Nobel Prize for..." format has been done enough now that it just seems lazy to me) and by the time I got to "the Button 2.0 is approximately a thousand times more useful" (emphasis mine, to highlight particularly clunky hyperbole) I was hovering over the tab with my finger over middle-click.
Here's the thing: this kind of overwritten article is so easy to put together and IMO so inferior to the clean, straight-up no-nonsense page on the Shapeways site that I don't feel "blog spam" is so inaccurate. I don't feel strongly enough to call it out as such as "benologist" did, especially as I know that to others on here (such as yourself?) it's not, but I hope this explanation helps you see it from both sides. To "benologist" this sincerely is blog spam and the fact that they linked to the cleaner article gets them an upvote from me.
