This is an experiment in short-form content on LW2.0. I'll be using the comment section of this post as a repository of short, sometimes-half-baked posts that either:

1. don't feel ready to be written up as a full post
2. I think the process of writing them up might make them worse (i.e. longer than they need to be)

I ask people not to create top-level comments here, but feel free to reply to comments like you would a FB post.
