There is probably a large hidden interest in China. One feedback site picked up 4,185 hits, putting China in second place, but another picked up only 1 hit on 29th June from Meituan Company, listening to “Nobody is Perfect” and another on 6th June from Shangdu, the China Construction Bank, who downloaded 1,672 megabytes. Where do the other 4,183 hits come from and why are they spotted by one site and not by another? My guess is that there is a very large hidden interest in ECE which we never see by feedback. Intellectually AIAS is the lead institute and all the uiniversities are following us.
