I approve of this.
As for what a "crush" is: I generally see it as something non-sexual, fun, and generally amusing. Most people give it a sexual connotation, which I understand, but I've never really given it one myself.
I probably shouldn't have left it "viewable: none", now that I think about it. It was a silly exercise. But one never knows what's going to come up in such a poll. . .
I think I've decided that, in general, I dislike the "veiwable: none" designation. I like my journal being open to public view too much.
