I think this is interesting to HN because of the blender thing, but at the same time I like that we try and keep things sober around here.
The not-breaking-guideline approach to posting this is much worse in my opinion. We often see tweets submitted that are little more than editorialized headlines and a link.
I suppose OP could have found an article that focuses more on the Blender aspect. Though, that still relies on the article to have a title relevant to HN. Personally, I am okay with what OP did.
Perhaps other posters have felt constrained by this, and yet not broken guidelines?
