I totally understand! Making my living working with algorithms also makes me especially interested, I just imagine the work you must have been doing!
So I make a try in thinking along of what might be possible.
Isn’t there some steering method in the algorithm that everybody is unconsciously aware of, but can still be amazed by when they think about it? For example, the fact that you don’t get an address from someone from your city (is it the whole city? A distance range?)
Or a throwback in time of when you first were creating it, seeing weird behaviour and had to adjust the algorithm that now seems like a dead simple choice?
Or a story on the options you have as a user to steer the algorithm, like repeated countries? You don’t have to explain how it works exactly, but why it was introduced can be interesting. And that there’s a team thinking about it and implementing it (what does that actually mean?).
My conclusion is that I really like the behind the scenes series (thanks for sharing the links!) to get a glimpse of what’s behind what I see in my browser. So anything on maintaining the algorithm I’d be excited to learn!
