* There is no proof in your statement that currrently 9X% of their users have fast internet connection. * Even so, it would simply be an artefact of them never bothering to optimize for people with slower internet connections. If they did optimize, a lot of their traffic would come from the so called "lowest common denominator" just as the blog post says it did for Google. * Finally I find the term "lowest common denominator" misrepresentative because it implies that optimization needs to cater to the slowest connection on earth, which is clearly not the case. If the average speed is above 90% of internet connections (as per Akamai report cited in the blog post) then the distribution of internet speeds is clearly skewed and there's value trying to even cater for median if not the minimum speed.
