~ can be used to display the home directory of other users as follows:

cd ~/billybob

Will put me in billybob's home directory (if I have permissions to go 
there).

~ is kinda magic in that by itself, it represents your home directory, 
but when it's followed by a '/USERNAME' it represents the home directory 
of USERNAME.
