Commentary on Campbell nominees?

Andrea pointed out this morning there do not seem to be many comments or recommendations posted in obvious places with regard to this year's slate of John W. Campbell Award nominees.

They are:

Saladin Ahmed

Gail Carriger

Felix Gilman *

Seanan McGuire

Lezli Robyn *

* second year of eligibility

So, have you read any of their books or stories? Surely the masses have some opinions? Yes? No?
