Yeah, this is addictive, and I'm spending here much more time than planned (but hey, I've just discovered Y!A :) ), yet it actually did help me with a couple of ideas and conclusions. And it is still much better than watching TV or drifting all over the internet - if you know how to touch the right buttons, it's actually quite a nice reasoning exercise. Plus, you actually get to talk to people from all over the world, all together, and I can't think of a better way to do this. ...But also of course that you're right, we do get slowly more and more virtual. So let's see, Preview, Submit, Sign Out, Close Window, Start, Turn Off Computer, Shut Down,... then Undress, Shower, Dress, Take Keys, Open Door and Go Out - hum, seems doable :).
(PS - not to forget - once out, Shut Door and Lock Door - nasty world out there...)
