This dock had the unique feature that if you receive an IRC Direct Message (DM) or name mention, it will make the dock icon for your IRC client (in my case, Pidgin) bounce and catch you attention. Considering how primitive the GNOME 3 notifications system is, this was the only truly reliable (an unobtrusive) way of working out whether someone was trying to talk to you. For me, the GNOME native notifications are intrusive and generally not that helpful. It is either "notifiy for all the things" or "nothing". Perhaps if you are using Empathy (the GNOME IRC client), things would be different.
I've been deliberately upgrading my fedora instance since Fedora 17, because I knew that AWN was no longer being developed. But sadly, a botched Fedora 20 "fedup" installation required me to start from scratch. :(
I knew there was a way to get AWN and its dependencies added back onto my system, because +Lucas Costi managed to get AWN onto his system when he joined Red Hat. So, off to the internet I went. I found a tutorial on YouTube that clearly explains what packages (last build of which was for Fedora 17) are required to make AWN function.
But, alas, changes in GNOME 3.10 renders the packages, and ultimately the solution described in the video redundant. The libdesktop-agnostic packages required here have a bug that renders them useless. Someone on Arch managed to patch it, but I'm not sure if it ever made it back upstream.

Some searching on ArchLinux forums suggests there is something wrong with the *-agnostic packages. Someone on Arch managed to patch it, but I'm not sure if it ever made it back upstream.
