Yet more things I didn't know

Pieman of Noodlepie mentions an architectural contest for the worldwide expansion of a Vietnamese coffee chain that is changing its name to "G7". He remarks:

One other thing, why the name G7? Does anyone know? Is it the number of different beans in the 'ground' blend? Whenever I hear the name G7 coffee I can't help but think of world summits and presidents decked out in Chinese dress or wearing sombreros. But that G7 is now the G8. G7 is so not coffee, no?

I had no idea what he was talking about, so I followed that link to G8.

Wow. I am so totally ignorant :> This seems like something I should be aware of, doesn't it?

I'm thinking it might be a good idea to just sit and read the Wikipedia for a couple hours every day...
