I'm impressed as well - but I do think many of us here are overestimating the size of the audience that sort of technical messaging would apply to. It being open is a big deciding factor for us on HN - but there's a much larger audience for whom it would simply dilute the messaging. (I'm guessing their product marketing team did a substantial bit of research on this before going live).

I could, however, see them building out a 'developer community'-focused microsite. But I wouldn't expect them to put anything related to that on their homepage, as it would likely be confusing and irrelevant to their target audience.
