To be fair, arguing that gopher has better usability than than google is sound, the thing is, google is much more functional.
Fidonet is an interesting lost tech to look at, I just wish I had been around at the time when it was in its prime, because it sounds fascinating. (or would have been at that time)
gopher is one technology which has totally dissaperad, ftp and usenet are probably, sadly, following it.
I know ftp is still used for mirrors and transferring stuff. but that is essentially it. almost no-one browses ftp servers.
usenet is going because very little new users are coming in, while everybody who has usenet these days, also has a webbrowser and someone else has phpBB (or unfortunately vbullitin)
