I like Fluent NHibernate and I think it's mature enough if you are going to start a new project. Using it on a new project should allow the Fluent NHibernate project to continue to mature as yours progresses. There is a possibility for breaking changes (as happened recently with the convention mappings) but you should be able to deal with those.
I've had a few issues with the mappings but the project is pretty responsive to bug reports and has mostly worked as expected.
One of the best advantages of using Fluent Nhibernate over vanilla NH is nice integration testing with PersistenceSpecification.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
