Everyone who uses language has their crutch words. These personal clichés fill a gap in common contexts, giving us a break from the burden of originality. Many are adjectives: academics have noteworthy, campus kids have awesome, and I have nice.
Almost anything positive could invite it: nice tune, nice scarf, nice work, nice idea. I also use nice in its narrower sense meaning subtle, fine-grained: a nice distinction. Both senses are familiar to modern ears. Go back a few centuries, though, and the word becomes a chameleonic stranger.
