Links

What is a link? Of course you know.
You join, connect or bind
two things, then more when on you go,
and more the more you find.

Should you apply a search machine
you jump from one to more,
until sometimes all links are seen
as just the next best door.

A link thus seen is temporary,
vanishes with a click.
Mechanic links would then be scary
if broken with a flick.
