Some of me wants to believe in your words, McGrath, but I have recently been witnessing the next generation of video conferencing on closed circuit, where people can essentially produce verbal/video clips, so a thread here might well be such a collection, which you could lay out on your screen, or just click on, and get a voice and a face with TV quality. In addition, you could set up a Mudcat Cafe in 3-D and people could choose a visual persona (or mask) if they didn't want their real face to be seen. When you click on it, it fills the screen and speaks, and then goes back down to the room size. And so on. I can't see people staying with typing when they can conveniently get face and voice. Typed messages could be attached as an alternative, or when you just want to read, but it will be an adjunct. Would I prefer to see someone demonstrate a fingerpicking pattern than write about it, yes. Would I rather see and hear you speak than read your words? I hate to say it, but yes. And I am a print person by trade and inclination.
yours, Peter T.
