Nick Heer on The Bullshit Web:
The vast majority of these resources are not directly related to the information on the page, and I’m including advertising. Many of the scripts that were loaded are purely for surveillance purposes: self-hosted analytics, of which there are several examples; various third-party analytics firms like Salesforce, Chartbeat, and Optimizely; and social network sharing widgets. They churn through CPU cycles and cause my six-year-old computer to cry out in pain and fury. I’m not asking much of it; I have opened a text-based document on the web.
