To conclude that Popova is a member if the “1%” based on some very speculative numbers is ridiculous, but not as ridiculous as Salmon’s apparent mind-reading skills or his supposed concern for the financial status of her readers.
Here's my take on it: Maria Popova made something nice that people like. Douchnozzles writing Reuters' endorsed blog posts made up some crap to get attention and clicks.
The top link in the Rehman post to the Reuters article is broken. Here's the one that works but I urge you not to give Felix Salmon your attention. What a carbunkle.
