I remember moaning about twitter reducing the number of characters people sent, and then yo! came out, and it was down to a single bit of data. That made me think 'what would even lower information content messages look like in a social network, perhaps half a bit or even less?'. I figured that a half bit of data would be where a social network sent some sort of hello message automatically with the same frequency the human user sent one manually, so given a message, it'd be 50/50 whether it was sent automatically or manually. Although I got to it theoretically, in the end, I thought it could be pretty useful practically, as a way of sparking conversations again when you haven't spoken to someone in a while, etc.

Maybe combined with ChatGPT we could even make those automatic getting-back-in-touch messages indistinguishable from the manual ones.
