Hi Biggie,
Thanks for your kindly reply!
But I don't agree with you for "no real value".
Both AI and EDU are abbreviations, why did you say not a common phrase?
Such as "NASA", "NATO", "HSBC", they are all abbreviations, but highly accepted.
AI is so hot in the world today, more and more companies use it in Education area.
In Chinese phonetic alphabet, AI also means "love, like".
In my opinion, if not with hyphen, aiedu.com? Not so easy to read and identify the correct meanings.
The AIEDU.us means American International
EduService .
"I" is near the hyphen "-", easily to type on the keyboard.
