This is blocking Google Analytics, Facebook Connect and New Relic on my site. How would DuckDuckGo prefer that startups measure traffic, ad ROI and site performance? What's the "right" way?
As a side benefit, when you start doing your own tracking from server logs, you gain valuable insight into where the gaps in data are from the third-party trackers, and precisely how many visitors are under counted.
This also seems bad for early-stage startups, where developer time is severely limited.
The whole idea that you need all the analytics is at least overblown and suffers from the streetlight effect. https://en.wikipedia.org/wiki/Streetlight_effect
for performance, chrome and firefox have built-in profilers, and chrome connects quite well to mobile.
