One of the things we believe as a team is that everything we make should be sealed with a blog post. Forcing ourselves to write up a short announcement post for every project we work on acts as a built-in quality check, making sure that we never call a project "done" until we feel comfortable telling the world it's out there. The problem was that up until today, we didn't actually have anywhere to publish those posts!

This blog post has been on my to-do list ever since I saw Daniel Stenberg’s blog post “This is how I git” (November 2020).

That is — as usual for this blog — we’re talking tactics, not strategy.
