Offline I was contacted with the suggestion to check the term "acorn" in one of my favorite sources - urbandictionary.com.
Obviously, this is in relation to the new logo for AnnArbor.com and not one of the definitions on the Urban Dictionary relates to the news business. But if you go there, be warned that some of the acorn definitions of acorn are adult oriented.
But when young people dump a new term on me, urbandictionary.com, is where I go to find out what it means. That way I don't have to look stupid, or unhip, by asking the person what the terms mean.
