Feedback from WWOOFers and Interns

I would find it most interesting to hear feedback from WWOOFers and Interns about there experience. Everything from expectations beforehand to a daily log, to what you got out of it when the journey was complete.

What do you hope to gain?
Why are you planning on doing this?

How was your day?

What do you wish you had learned?
What would you have done differently?
What would have improved the experience?

And, did you feel like you were being treated as a student, or a slave?

As a wwoof host, I'm interested in this topic. One of the questions on my fairly extensive application is if they are interested in learning about perma culture.
Last year I had three seperate weeks where I invited wwoofers to come who were interested in learning plant id and permaculture basics and part of their job was to listen to my spiel and critique my teaching!
I always ask about prior wwoof farms and am curious how we measure up.
