I have spoken at several code camps and have never seen Microsoft ask for any evals of speakers. In fact, that would somewhat go against the CodeCamp idea where it is run for and by the community and is technology/language agnostic.Being run for/by the community doesn't preclude giving the community a say. ;-)
Perhaps speaker evals at Code Camps will be next. I give professional presentations fairly often fwiw and I've always regarded such evals as a check that my presentations are still satisfying the audience. Unless the audience is asked, preferably anonymously, how can you be honestly self-critical of your perfomance?
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
