What's the difference pipe vs redirection is the following case case.

When I execute party, it brings up a chat line. Ie

m-net% party
Welcome to PARTY! Type '?' for help:
triluda: my hero
mickeyd: are we cheech'n'chongish enough?

When I do the following
m-net% party | /dev/null
zsh: permission denied: /dev/null

I get permission denied.

But when I do something like the following
m-net% party > /dev/null
Welcome to PARTY! Type '?' for help:
e

The output from party gets redirected to /dev/null

What's the difference between the two? Ie, why do I get permission
denied when I try to pipe party to /dev/null?
