Quite an interesting point. You suggest that the act of doing something mechanical does add emotional value to it. But what adds even more is time. Look at your Facebook posts from five years ago, or even your tweets from last year. Time passing makes you feel different about things.

I think the emotional appeal of those pictures pasted to the wall comes from the sheer age of them, in sharp contrast to the high tech equipment in the same room.

I am more concerned about the preservation of our postings than the emotional value. Things that really matter will produce the same emotions regardless of the medium.

You've hit the nail on the head. I (very) occasionally visit a messageboard that was active about a decade ago out of nostalgia.
