Re: Acoustic Couplers...
For us oldies the Net was an engineering feat that we learned to use from its most basic level up. In those days, online instant messaging was "talk user@ip address" and the only reason we started to use X was because it gave us more command lines on one screen :).
That said, the whole hypertext approach was a major improvement because it tied in more tightly with the then most important development work on the Net: interoperability, a feature that companies like Microsoft (who were very late to the party) have tried to bury ever since..
