Hacker News Reader

Are you really seeing all that loading on the site? Where are you located? The only tracking code being included by us is Google Analytics. There are 4 youtube embeds on the page too that could be loading in some other code.

BuiltWith contains data about both the current and past usage of services gathered from scraping the page, but also from a bunch of other (not always) reliable sources.

How do they calculate that? Chrome Network dev tool just shows Google/Youtube/Doubleclick resources.
