In anticipation of any request for citatation, a recommendation for this engaging little book, found in the computer section of Borders:
_Rules of the Net_ by Thomas Mandel and Gerard Van der Leun, Hyperion Books.
One of the utter beauties of the Internet is that anyone, anyone, who can plug a terminal into a keyboard and hard drive can get on and talk to others. So what if someone still uses Pine? Pine is the way that dissidents in third world countries are getting their messages out to others to find the way to freedom. So what if Telnet is going defunct? People in China still use it as a way to circumvent government censorship. So what if someone doesn't have the latest system--so long as the emails get out, and can go back.
