Sometimes I do feel like [corpus linguists have already answered my question](http://andreadallover.com/2013/08/25/unsurprisingly-corpus-linguists-have-already-answered-your-question/), but sometimes I feel like they didn’t ask very interesting questions in the first place, and that’s why I continue to stumble along, covering ground they have already covered. My best example of this? The corpus linguistic notion of *lexical diversity* doesn’t seem very interesting — at least not in the forms I have encountered it. I am trying to use it as a way to think about the nature of speech genres. (Please don’t ask me to say more: I don’t have any answers at all. Only questions that CL hasn’t answered for me.)
