I wonder if the absence of those excellent contributors is a sign of the times. I think we might be witnessing the death and obsolescence of the home computer.Technologies change. Letter writing is long a lost art, largely with the advent of the telephone and maybe the typewriter. Now with the cellphone, you don't even have to get home, compose yourself, and make a bit of a production out of a call. Now just fire off a quip.
With the computer, you could sit and ponder, elaborate on your point and explain yourself fully and at ease. The cellphone quip comes so much easier even if it leaves readers wondering what you meant. Just like the old letter writers asked themselves why should I bother when I can just give a call, maybe the old posters are saying I don't do all that work and stuff anymore now I got my instant phone.
Another blow to the great pleasure of deep thinking and reflection and deep thinking music as well.
