Rethinking praise

I just read this article on the risks of overusing praise and lines like "good job" with our kids. This is definitely food for thought for me. I'm sure if I counted the number of times in a day that I say "good job" to little a., I would quickly run out of fingers. What are your thoughts on this - is praise something you're wary of, and if so, have you replaced it with some other kind of reaction?
