Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

What's wrong with using "rm"?

Seriously though, there's no difference in what they fundamentally do aside from unlink not working on directories; unlink works just as well on regular files as it does on links.
unlink has nothing to do with symbolic links.
Note on some systems unlink() *can* unlink directories, with the tree underneath not being reaped until the next fsck.
