You probably know more about linguistics than I do (disclaimer: very little), but I suspect you might not fully appreciate that "etymology" here is probably just a mere translation of the very well established discipline of studying the history of Han characters in East Asia...
Alternatively, would you have a better suggestion on what to name this in English, if it shouldn't be called "etymology"?
Also, what specifically would you recommend taking with a grain of salt from the website -- that the data might be wrong? Or are you implying that, notwithstanding a possible name confusion, that the study of evolution of characters is somehow not a worthy exercise for "serious" scholars?
