Hi, thanks for your nice and impressive article and for mentioning our original paper about the generalized friendship paradox. I’m one of the authors, Hang-Hyun Jo. I’d like to say that my friend and colleague Young-Ho and I are trained as physicists not as sociologists. I admit that our work is basically sociological, so that we could be (some kinds of) sociologists too. At least in my case, I prefer to be called a physicist. Indeed, one of my research interests is social physics, you might have heard of it.
Have a nice day, then.
