It is our banter, our very thought process.
For you perhaps. For me, it speaks no more than a conversation in the hall, or on the phone, or in the checkout line in a grocery store. Or a photograph, or something I saw with my eyes. The thing that keeps all of these in place, regardless of medium, is the human brain -- and it's truly fascinating. I have near instantaneous recall and a minimum overhead for this recall, and unimportant things are deleted automatically! :)
Is organizing detrimental? Well, no. Organizing can be applied to any medium, not just in the computer realm. Yep, in your brain too. It's skill. If we rely on computers to substitute for our minds, we are doomed. Admittedly, this might have better applications than email, such as, per se, the miserable failure that was the "Semantic Web".
I have a desire to play with computers in my spare time, but that desire is getting crushed because I stare at too many monitors at work. Best of luck to you! It *is* an interesting subject. But I will keep my brain. I like it. It also doesn't hurt my eyes when I try to use it.
