Well Paul, I never laid claim to any originality of thought in what I wrote in my post here. All sheep tend to think the same.
I just thought I'd mention what I did. Sorry, it won't happen again, I promise.
I must admit that I got bored with reading the comments under the post of that animation anyway, and there's doubtful knowledge to be gained in such discussions, since opinions tend to prevail. So, I went off to see what Wikipedia said on the matter and posted the URL on this site. There was a good point made about Compuserve too, in the comments. I don't think the Wikipedia item mentioned IBM's SNA. I recall that EDS used to have a superb overview of the WWW/Intranet
By the way, I listened online to telekaster's "pyramid", and captured it with Audacity. Getting the right volume threshold for that music is a bit tricky though - I am still learning to use Audacity.
