As an intersex person who gender transitioned to male, I think about both intersex and trans issues a lot. The Intersex Roadshow is a blog focused on issues central to the live of people with sex variant bodies, and I only post information and thoughts on trans issues here that center on intersex experience. Recently, however, I started up another sibling blog to focus on trans issues. It's called TransFusion, and you can find it here: http://trans-fusion.blogspot.com/.
I have written two prior posts on The Intersex Roadshow that discuss intersections between intersex and trans gender experience. You can find them here and here if you are interested.
