Telegraph

Telegraph

The 19th century telegraph and railroad provided the first habitus
for virtual communities. The railroad objectified time and created
the potential for liaisons at a distance. The telegraph workers used
their spare time to talk to one another - friendships and marriages
resulted. The telegraph used a protocol stack reminiscent of tcp/ip
- the layers ranged from hardware to application, with redundancy
and several layers of coding, including addressable messaging
systems, in-between. The telegraph has its parallels in ascii, in
terms of bandwidth; visual telegraphy never really caught on. The
telegraph communality was celebrated in popular literature and song.
For a long time I've been interested in the apparatus itself as
well; recently in Omaha, I was able to buy a small station consist-
ing of a sounder and key. Soon I'll have a telegraph between my
table and Azure's desk, about twenty feet away.
