Hums are better as they give greater weight to people who are more vocally in support (or in opposition) to the assertion. Research shows([1]), that the one humming loudly for acceptance, will also volunteer to review and contribute code. The one humming loudly against is going to jump up to the mike in all future meetings and tell the group that they're doing the wrong thing. Those who hum softly will go back to reading their email.
