Ah, I knew my operating systems calss would come in handy one day. :-)

As has been already stated, a symbolic link is a file that points to a
file's location; delete the original and your link is useless. This is
similar to a Macintosh "alias." (A windows 95 shortcut is much weaker.)

Each file in your unix filesystem is represented by an i-node. This is
part of the directory structure. When you create a file, you are creating
an i-node and a hard link from the i-node to the file inside a directory
somewhere (say /home/foo). When you create a hard link using ln (say
/home/bar/lalala), you are creating a second hard link to the i-node. You
aren't creating a second file. Basically, the file is in two places at
once.
