Thank you. My reply to C. Mackinnon, above, responds to some of what you write.
Wrt aesthetics, I'd agree not putting too much emphasis on appearance (changing fonts for example would be too much). Otoh, having a presentation device like smallcaps can IMO make key names stand out, and provide useful variation to a block of text. All caps, bold, and italic are other devices we use for that.
But again, I don't mean to make a big issue of this - just something that occurred as I was adding a public domain bio that used smallcaps to a profile.
