Email, as a medium, prompts us to think (at least for a few seconds), not "generate human tokens". Sure, we may feel being "communicative" or "productive" while chatting or Slack, but (in my experience) it is not always the case.
I've considered doing this a few times, but have to admit I've never actually got round to sending people appreciative emails, maybe this blog post is the prompt I need.
There's a lot of makers on HN, has anyone here ever received emails about things they made?
I used to be fairly active on r/generative, someone once DM'd me to show me a pen-plot they'd made based off of something I'd made, and it made my whole week.
It feels somewhat hacked together (because, largely, it is); and there are significantly more bots than people using it (which is somewhat self-fulfilling).
But when I read the leaked/disclosed emails from founders during tech's boom in the late 00-s and early 10-s, I'm left feeling like: this is kinda nice.
You don't need to write long prose, email chains are reasonably self-contained, can include practically anyone and since nobody seems to have a total dominance on mail clients; they pretty much stick to the lowest common denominator. (though, HTML seems to be very much accepted behaviour for email clients, even though it was NOT when I grew up).
So, in the end, it's the safest medium to reach the most people, and incidentally it's also the most "comfy" in that I can optimise my own experience of email if I want to. Nobody cares if you use outlook/gmail/thunderbird/mutt or whatever. It's just email.
This is a pretty strong contrast to the modern web which pretty much requires Chrome or modern messengers which require/enforce their own first-party clients. Even if they happen to support federation (like Teams) which isn't a given.
