it does, because we care about a number of things, including: 1. Technical implementation (and alternative ways of implementation). 2. Freedom (keeping things within google's walled-garden or not)

Your average user (who doesn't necessarily know anything about software) doesn't really care about 1, and probably doesn't care about 2. They care about speed of the page, data consumption of the page, and maybe the look-and-feel of the page (bloated vs sane).

When I say HN user, i mean technically informed and most often skeptic people.

The distinction matters.
