David Rothkopf, being both funny and acute:

Buzz words are important in the wonkosphere because people are very busy going from conference to conference, periodically stopping to Tweet about who they bumped into and how they influenced them, and they have very little time to really think about anything. So if you can take an idea, reduce it to a couple of key, easily digestible, tasty ingredients, and wrap into a piece of shiny gold foil you have ... a Reese's Pieces Mini. Well, actually, you have something just like it, but not quite as tasty; you have a candidate for buzz-term of the moment.
