i would just say like i said something is lost when you don't have that face to face when you don't get to sit down with someone to make sure their needs are meet is not, the thing that you do with the tutorial is that you can only it is basically done one way i mean someone can go thru it faster than someone else but when you are doing face to face you can kind of get a feel for where your audience is and whether you need to slow it down or focus on one aspect so i think a little of that human touch is lost it becomes a little more impersonal than i like
