The original point was that urandom draws entropy from random, and that it is an an inobvious and unintentional drain on the entropy pool. At least that's how I read it. I certainly have programs which draw on urandom simply because it's a convenient source of meaningless data. I have several fewer since this discussion started, though, now that I have looked at the easy alternatives.
