I remember getting my first piece of email from outside the university and thinking "Wow, this is really cool! But who else do I know that I can send email to?" (A contemporary parallel might be "But who else bikes to work?" Not the majority of people I know.) And you had to know the "bang-path" – you had to route the email through all the servers between yourself and your recipient. It really wasn't something the masses were going to adopt. And each of those "hops" in the path was a phone call between servers, and toll calls weren't cheap then. Delivery to other sites typically took hours, sometimes days.
