Tim Berners-Lee tweets that 'This is for everyone' at the 2012 Olympic Games opening ceremony using the NeXT computer he used to build the first browser and web server. The chief effect of the architectural difference is to shift the distribution of latency within the loop. Improving latency for one scenario can degrade it in another.
