Both of these posts are now out of date - for more info:
I named the new post Part Deux forgetting that I had made a part II already :-) It seems when I did that, I liked "Slight" hinting better.
This post is now, as far as I'm concerned out of date. Please see this updated post for more info: http://jaysonrowe.blogspot.com/2012/08/improving-fedora-font-rendering-part-ii.html
One of the adjustments when moving from Ubuntu to Fedora was font rendering. Out of the box, Fedora's font rendering isn't bad it's just different. Often fonts look different, than on Ubuntu.
I first came across this blogpost from Jason Brooks which actually pointed me to this blogpost. After following those steps, they looked better but still not quite right. So...like any good nerd, I did more research which led me to this post on the Fedora Forums talking about Infinality (which was also mentioned by a commenter in my Fedora Setup Guide post as well. After installing the repo and installing the following packages, my fonts are finally perfect! This is why I love the internet :)
To get everything set up (in a terminal):
$ sudo rpm -Uvh http://www.infinality.net/fedora/linux/infinality-repo-1.0-1.noarch.rpm
$ sudo yum -y install freetype-infinality fontconfig-infinality libXft-infinality
Also note that before doing this I did back out the changes I'd made previously, and rebooted, getting me back to a default config.
