I used the word "disintermediate" in a sentence yesterday.
Once to my manager, who didn't bat an eye - no, she chimed right in with "Going forward". See, we're both singing in the same choir.
And once to my colleague, who has a brand-spanking new undergraduate degree in Linguistics. She gave me a look. The calm and level look that says, "That is so not a word and I'd rather start H-dropping than speak your tortured corporatese."
