Polari is the new GNOME IRC client that is not (yet) in Fedora proper. If you want to give this new application a go, i have packaged it up and created a new fedorapeople repo for it.
To set this up on your Fedora machine, first download the .repo file:
sudo curl -o /etc/yum.repos.d/fedora-polari.repo http://repos.fedorapeople.org/repos/ryanlerch/polari/fedora-polari.repo
Then install polari:
sudo yum install polari
