I don't usually mention where I work, but it's very relevant to this point about showing interest in the company. (I run IT for Vistaprint.)

I was interviewing someone for a mid-level systems engineering position, and the interview seemed to be going well-enough. I always wrap up with a few minutes for the candidate to ask questions about the company, and the only question this candidate had was "Have you guys ever considered building a website where people can design and order business cards?"

Blink; blink; WTF? Uh, yeah, we did about $250M in business that way last year, so I'd say we've given it some thought.

An employer is going into the interview with some need that they're hoping you can fill. That need is almost certainly not "I need to make sure the next person in the door can pay rent and buy food." so you shouldn't go into the interview focused on that either. By all means, you have your own set of needs that you need filled, but in the interview, focus on the employer's need, not your own.
