Livre d'Or

I'm interested that you don't mention text message at all? I definitely have friends for whom that's the preferred method of communication.

I feel like the GCHQ deserves a shoutout, too, if you're worrying about government data collection :)

Personally, I prefer email. I'd say that compared to you I probably feel less obligation to write thoughtful emails and more obligation to write thoughtful dw posts, which affects relative rates of production.
