I've noticed that there seems to be no consensus, among those who self-identify as atheist or agnostic, as to the difference between the two.
Most agnostics I've ever known personally say they are "agnostic" because they do not believe there is proof of a God, but that they do not exclude the possibility, and distinguish themselves thus from "atheists". Yet most who self-label as "atheist" do not define "agnostic" that way. It gets a bit confusing.
