This is completely BS. What is he showing here? That a static copy of wikipedia "news"[0] is faster than a full featured news website. Is this just a contrived ad? My news aggregator also achieves 100% performance[1] but I don't dare to use that info to make such a irresponsible claim. Is also some orders of magnitude easier to be a news curator than a news producer.

[0] Is hard to consider local news like "Two policemen and a polio vaccinator are shot dead by gunmen on motorcycles in North Waziristan, Khyber Pakhtunkhwa, Pakistan" relevant news.
