GOAT = Greatest of all time?
General rule of thumb with communication: Try to avoid acronyms, because chances are most people will have no idea what you're talking about. If you do need to use them, make sure you very quickly define what the acronym is.
FWIW: Even the Google doesn't know what GOAT blogs are. Searching for GOAT blogs brings up blogs about goats: https://www.google.com/search?q=GOAT+blog&rlz=1C1GCEU_enUS99...
So this friend of mine is currently reading a history book in French. Full of acronyms, not recognizable in the current international use. SMI, DTS, OPEP, OTAN, OCDE... (Those should have been spared from localization. If born in English, so they should be preserved; in French, the rest should adapt to that - at least in the acronym.)
Pretty sure that's still on the NATO logo as the initialism of the French translation of NATO.
That's because GOAT is a sports term that is slowly entering general use.
If you Google "GOAT sports," Google not only knows what you mean, it explains GOAT.
