Well I did say that I supposed I am an old fart. You did a good job citing all the arguments I would use to refute what you are saying - so 'nuff said. If you extropolate your arguement, we are all heading towards the human blobs in Wall-e. On the flip side, I agree that it is a good way to express what is on your mind without the finality of the spoken word until you hit the send button....
