I think 'caring' works pretty well for most people. What I mean is this: care about what they're doing. Ask after it. Ask if there are problems, or they need help, or about what problems they faced. This lets them know that people do care about the results and are watching, without being authoritarian or putting them on some kind of pedastal. I think you can be a mediocre worker (I've met some really awesome coders myself, guys like Andrew Tridgell, and compared to them, I'm as mediocre as it gets), and still put in your best effort, be diligent at what you do, and so on.
