After a long pause in our correspondence, this morning I wrote to an old friend in Belgrade. When I tried to send the message via electronic mail, it bounced. “Domain not found,” the problem was tersely explained. And then I noticed that the electronic-mail address had “yu” as the domain name, which used to stand for “Yugoslavia.” The same two letters were used in many other contexts, including car stickers that were obligatory when crossing national borders. And it was used in Serbia long after Yugoslavia had fallen apart. Thus I added a few more words to my message and sent it to my friend by snail mail. “Our country of birth does not exist any longer even in the virtual world,” I wrote wistfully. A quick search on the World Wide Web shows that the domain name can still be found in many country listings, but it is actually defunct. The very last death of Yugoslavia, I guess.
