In some limit cases, that's true, but I've literally heard the following two questions asked in the last week (one directly to me, one in the same room I was in; these are not FoF cases):

What is SCOM? What is MRTG?

In both cases, knowing nothing about the domain gets you exactly the answer you want. I think far more often than it doesn't, a relatively naive query to Google with a followup query or two with certain words excluded will get you what you need.
