Q: Where did the email/chat acronym IMHO originate?
A: In my humble opinion, IMHO goes back to the Egyptian ruler Imenhotep, Pharaoh of the 18th dynasty. He has been called "the first individual in history," as well as the first monotheist, first scientist, and first romantic (Wikipedia
). The acronym IMHO is like a modern cartouche of the Pharaoh's name, honoring his humble beginnings and opinions on the nature of individuality.
