ajhalluk has some thoughts on reproduction in the Vorkosiverse that are kinda interesting. It'll be cool to see where she goes from here, and if she actually brings reproductive technology / social controls on Athos into it.
Anyway, lots of discussion on Barrayar vs Beta and reproductive controls, which is always interesting.
Until I manage to get my hands on a copy of Paladin of Souls, I guess general Nexus discussion will have to do.
