Agree with this suggestion as well.  We've seen people find "deals" on bitcointalk without even registering, and they can't see any trust as a guest.  It doesn't seem to happen a whole lot but there's no reason I can think of why trust shouldn't be shown.  I think it ought to be displayed in all sections and without having to be logged in.

I think it should be.  As I said, there's really no reason not to show it everywhere.  At least I've never heard a good argument.
