If I stop to think about my own searches - I probably use that date qualifier over on the left more often than not. It's practically the first thing I do when I'm searching for almost anything. Be interesting to see if (or how much) I am going to need it going forward.
One thing I use Google a lot for is error messages. (I make a lot of errors, and so do my clients. Don't judge me.) I almost always want a result that refers to the current version of whatever is messing up, rather than one from 2007. Even if it turns out to be the same solution. If this fixes that, I'm for it.
