Nope, "in the loop" is just me mangling a slang phrase I personally use -- "Keep me in the loop" -- which means "keep me informed in a real time manner". It's not the first odd phrase I've put together, as my girlfriend likes to remind me: "I don't words well".
I remember once contacting Sun for info on software many years ago and received an email where they promised that someone would "reach out to me".
I didn't want to be reached out for - I just wanted some text answering my question.
