It seems a bit arrogant to say "I don't like this particular article, therefore the community is primitive." An Animated GIF messaging library is certainly of interest to a majority of hackers.
I simply made an amusing (to me) observation. I had earlier thought Pinterest seemed like MacGyver for people into crafts (at least that's the kind of thing my wife kept getting excited about). That's not to disparage HN or Pinterest or MacGyver for that matter.
As a die hard McGyver fan, I'm offended you'd compare him to a subset of stay at home mom's pinning pictures of other women with flat abs as "motivation." Ok, occasionally they post some pretty cool stuff, but mostly it is the former.
