All the links I posted are undergrad-grad level which is what I'd expect most HN visitors to be interested in. I assume not many 5th graders frequent HN (perhaps I should account for parents of 5th graders).
While KA is definitely well organized, esp. for kids, "miles better" is hyperbole. There are other resources for young learners such as mathvids, brightstorm.com (and others) with little or no mention on HN.
There are also cheap/paid/freemium resources for kids - eg. mathtv.com and yourteacher.com (I think yourteacher has been around for a while.
My overall point is that - regarding this topic, HN seems to have a rather narrow view or is completely unaware of existing resources.
