I learned to take asking questions of the interviewer really serious since the few times I was so enamored by the company, I didn't ask the right questions. A few months later, I was miserable. The three main questions I ask are: What do you do that separates yourself from your competition? Who do you see as your biggest competitors? How much have you been working with (insert some cutting edge technology - lately for me, it's been stuff like Backbone.Js or Parallax Scrolling)? In terms of barometer, it gives me a solid idea of where the company is going, and how they view possible new technologies. These also tend to get, "Wow, that's a great question" from whomever is interviewing me.
