I tested Redcore Linux tonight ( http://redcorelinux.org/ ) , I'm intrigued by it since it's a small and non-bloated gentoo installation, and the installer has the things I want (Fulldisk encryption etc).
Easy and fast to set up.
I like it because it takes out the pain of setting up a gentoo installation.
This definately makes it easier for people to get into gentoo.
I've run sabayon before, and that feels like a bloated OS, while Redcore is the snappy small install.
Also - very important to me is the fact that the graphics drivers works out of the box, same with steam. So yeah, redcore linux looks very promising indeed!

I'm also going to start to write on my blog each time I test a new OS, write down what I like about it, what I dislike and how it works for the kind of work I do (3d\coding\games etc). And write reviews from my own point of view. As many of you know I change distros all the time ,so writing about them can become my next hobby.
