Well, no, not really, since we are revolving with it. I haven't heard of this notion, but if true, I would suspect the number was derived and calculated from some evidence that implies that the early universe had some rotational momentum shortly after the Big Bang, and not from some "real time" measurement". What is not clear to me is, since the Big Bang is actually an expansion of space, what could it possibly be revolving around? Such a thing implies a "preferred" location in space-time, a sort of absolute reference point of some kind?

When observing the movements of the universe, scientists don't get to sit back and measure the speed. Instead, they measure the relative velocities of other stars to our own. By adding those up, they are able to make calculations about the speed of rotation for a galaxy (such as the milky way). Keep in mind. It takes ~365.25 days for the earth to revolve around the sun. Do you think you can really see it moving? Of course you can. The earth is also travelling a great distance. Believe it or not, the planet is moving rather quickly.
